Abstract

International audience; Planet–planet scattering is the leading mechanism to explain the broad eccentricity distribution of observed giant exoplanets. Here we study the orbital stability of primordial giant planet moons in this scenario. We use N-body simulations including realistic oblateness and evolving spin evolution for the giant planets. We find that the vast majority ( 80%–90% across all our simulations) of orbital parameter space for moons is destabilized. There is a strong radial dependence, as moons beyond 0.1 R Hill are systematically removed. Closer-in moons on Galilean-moon-like orbits (

Abstract

International audience; We present multiple lines of evidence that gas in the Taffy galaxy system (UGC 12914/5) is in a highly disturbed state as a result of a recent head-on collision between these two gas-rich galaxies. Building on evidence of large quantities of warm molecular hydrogen in the Taffy bridge, and evidence of boosted [CII] emission from Herschel, we observed the Taffy system with ALMA in the CO 2-1 and 3-2 lines, and with the McDonald Observatory VIRUS-P IFU system in the visible light. Strong emission lines were detected from the galaxies and in the bridge with VIRUS-P, showing two dominant velocity components over much of the bridge and parts of both galaxies. We made a detailed analysis of the excitation properties of the ionized gas, finding that a significant amount of the high-velocity component of the bridge gas was consistent with shocks with velocities of 200-300 km/s. Two distinct filaments of ionized gas were found between the galaxies. Our ALMA observations also showed that the dense molecular gas is also highly disturbed. The most remarkable aspect of the ALMA observations is the discovery of a tangled web of molecular filaments in the bridge. The individual filaments are typically 1 kpc in length, are almost unresolved at 60 pc resolution in the other dimension. They also contain clumps that have broad line widths of 80-150 km/s. Although some of the filaments are associated with a prominent extragalactic star formation region located in the bridge, most of the filaments show little obvious sign of star formation despite their apparently high molecular surface densities. Given their high surface densities, it is not clear why the filaments are not forming stars, unless they are magnetically supported. One possibility is that they represent transient density enhancements in a supersonic turbulent multi-phase fluid created in the aftermath of the high-speed collision.

Abstract

International audience; Most of the radio sources observed by VLBI, some used as defining sources in the International Celestial Reference Frame [ICRF2], show instabilities in position. These instabilities may be caused by astrophysical phenomena occurring in the central VLBI region of these objects (i.e., active galactic nuclei). On this basis, we have begun to characterize the signal included in the available VLBI position time series. Often, position instabilities happen along a preferred direction. There are cases, however, where two directions are distinguishable. The first scenario is consistent with a regular emergence of jet components from the VLBI core; hence, causing shifts of the radio emission centroid. On the other hand, the second scenario may give clues to the presence of a second black hole within the system that has its own activity offset from that of the first black hole. Comparing these directions with the orientation derived from radio-optical position offset brings further insights into astrophysical phenomena within active galactic nuclei.

Abstract

International audience; We present MaxiMask, a contaminant detector for ground-based astronomical images based on convolutional neural networks (CNNs). Once trained, Maxi-Mask is able to detect cosmic rays, hot pixels, bad pixels, saturated pixels, diffraction spikes, nebulous features, persistence effects, satellite trails and residual fringe patterns in ground based images, encompassing a broad range of ambient conditions, PSF sampling, detectors, optics and stellar density. Individual image pixels can be flagged through semantic segmentation, based on high-resolution probability maps generated by MaxiMask for each contaminant, except for the tracking error probability which is assigned by another dedicated CNN. Training and testing data have been gathered from a large dataset of simulated and real data originating from various modern CCD and near-IR cameras.

Abstract

Classical hot cores are rich in molecular emission, and they show a high abundance of complex organic molecules (COMs). The emergence of molecular complexity is poorly constrained in the early evolution of hot cores. Using the Atacama Large Millimeter Array we put observational constraints on the physical location of COMs in a high-mass protostellar envelope associated with the G328.2551-0.5321 clump. The protostar is single down to ~400au scales and we resolve the emission region of COMs. Using thermodynamic equilibrium modelling of the available 7.5 GHz bandwidth around ~345 GHz, we detect emission from 10 COMs, and identify a line of deuterated water (HDO). The most extended emission originates from methanol, methyl formate and formamide. Together with HDO, these molecules are found to be associated with both the accretion shocks and the inner envelope, for which we estimate a moderate temperature of $T_{\rm kin}\sim$110 K. Our findings reveal a significant difference in the distribution of COMs. O-bearing COMs, such as ethanol, acetone, and ethylene glycol are almost exclusively found and show a higher abundance towards the accretion shocks with $T_{\rm kin}\sim$180 K. Whereas N-bearing COMs with a CN group, such as vinyl and ethyl cyanide peak on the central position, thus the protostar and the accretion disk. This is the first observational evidence for a large column density of COMs seen towards accretion shocks at the centrifugal barrier at the inner envelope. Since the molecular composition is dominated by that of the accretion shocks and the radiatively heated hot inner region is very compact, we propose this source to be a precursor to a classical, radiatively heated hot core., Comment: Accepted for publication in A&A (17 pages, 9 figures).

Abstract

13 pags., 6 figs., 5 tabs., SN 1572 (Tycho Brahe's supernova) clearly belongs to the Ia (thermonuclear) type. It was produced by the explosion of a white dwarf (WD) in a binary system. Its remnant has been the first of this type to be explored in search of a possible surviving companion, the mass donor that brought the WD to the point of explosion. A high peculiar motion with respect to the stars at the same location in the Galaxy, mainly due to the orbital velocity at the time of the explosion, is a basic criterion for the detection of such companions. Radial velocities from the spectra of the stars close to the geometrical center of Tycho's supernova remnant, plus proper motions of the same stars, obtained by astrometry with the Hubble Space Telescope (HST), have been used so far. In addition, a detailed chemical analysis of the atmospheres of a sample of candidate stars had been made. However, the distances to the stars remained uncertain. Now, the Second Gaia Data Release (DR2) provides unprecedented accurate distances, and new proper motions for the stars can be compared with those obtained from the HST. We consider the Galactic orbits that the candidate stars to the SN companion would have in the future. We do this to explore any kinematic peculiarity. We also locate a representative sample of candidate stars in the Toomre diagram. Using the new data, we re-evaluate the status of the candidates suggested thus far, as well as the larger sample of the stars seen in the central region of the remnant., Funding for the DPAC has been provided by national institutions, in particular the institutions participating in the Gaia Multilateral Agreement.

Abstract

[Abridged] Molecular filaments have received special attention recently, thanks to new observational results on their properties. In particular, our early analysis of filament properties revealed a narrow distribution of median widths centered at a value of about 0.1 pc. Here, we extend and complement our initial study with the analysis of the filamentary structures observed in eight nearby molecular clouds. We use the column density maps derived from Herschel data and the DisPerSE algorithm to trace a network of filaments in each cloud. We build synthetic maps to assess the completeness limit of our extracted sample and validate our measurements. Our analysis yields a selected sample of 599 filaments with aspect ratios larger than 3 and column density contrasts larger than 0.3. We show that our sample is more than 95% complete for column density contrasts larger than 1, with only 5% of spurious detections. On average, more than 15% of the total gas mass in the clouds, and more than 80% of the dense gas mass, is found to be in the form of filaments, respectively. Analysis of the radial column density profiles of the 599 filaments indicates a narrow distribution of crest-averaged inner widths, with a median value of 0.10 pc and an interquartile range of 0.07 pc. In contrast, the filaments span wide ranges in length, central column density, column density contrast, and mass per unit length. The characteristic filament width is well resolved by Herschel observations, and a median value of 0.1 pc is consistently found using three distinct estimates based on (1) a direct measurement of the width at half power after background subtraction, as well as (2) Gaussian and (3) Plummer fits. The existence of a characteristic filament width is further supported by the presence of a tight correlation between mass per unit length and central column density for the observed filaments., Accepted for publication in Astronomy and Astrophysics

Abstract

Exoplanet surveys have confirmed one of humanity's (and all teenagers') worst fears: we are weird. If our Solar System were observed with present-day Earth technology -- to put our system and exoplanets on the same footing -- Jupiter is the only planet that would be detectable. The statistics of exo-Jupiters indicate that the Solar System is unusual at the ~1% level among Sun-like stars (or ~0.1% among all stars). But why are we different? Successful formation models for both the Solar System and exoplanet systems rely on two key processes: orbital migration and dynamical instability. Systems of close-in super-Earths or sub-Neptunes require substantial radial inward motion of solids either as drifting mm- to cm-sized pebbles or migrating Earth-mass or larger planetary embryos. We argue that, regardless of their formation mode, the late evolution of super-Earth systems involves migration into chains of mean motion resonances, generally followed by instability when the disk dissipates. This pattern is likely also ubiquitous in giant planet systems. We present three models for inner Solar System formation -- the low-mass asteroid belt, Grand Tack, and Early Instability models -- each invoking a combination of migration and instability. We identify bifurcation points in planetary system formation. We present a series of events to explain why our Solar System is so weird. Jupiter's core must have formed fast enough to quench the growth of Earth's building blocks by blocking the flux of inward-drifting pebbles. The large Jupiter/Saturn mass ratio is rare among giant exoplanets but may be required to maintain Jupiter's wide orbit. The giant planets' instability must have been gentle, with no close encounters between Jupiter and Saturn, also unusual in the larger (exoplanet) context. Our Solar System system is thus the outcome of multiple unusual, but not unheard of, events., Comment: Abstract abridged.

Abstract

At least 30% of the FGK-type stars host "hot Super-Earths" with sizes between 1 and 4 Earth radii and orbital periods of less than 100 days. Here we use N-body simulations that simultaneously model gas-assisted pebble accretion and disk-planet tidal interaction to study the formation of hot super-Earths systems. Our results show that the integrated pebble mass reservoir primarily controls the system fate. A simple factor of ̃2 difference in the pebble flux bifurcates the final outcome of our simulations between systems of hot super-Earths or hot- Neptunes (≤20 MEarth) and systems containing multiple massive cores able to become gas giants (≥20 MEarth). Simulations with low to moderate pebble fluxes grow multiple super-Earths that migrate inward and pile up at the disk's inner edge in long resonant chains. We follow the long-term dynamical evolution of these systems and use the period ratio distribution of observed planet-pairs to constrain our model. We find that up to ̃95% of the resonant chains become dynamically unstable after the gas disk dispersal. Supporting previous studies, our simulations match observations if we combine a fraction of unstable and stable systems (e.g. 95% unstable plus 5% stable). Our results also reinforce the claim that the Kepler dichotomy is an observational artifact. Finally, our results predict that in every hot super-Earth system at least some hot super-Earths should be ice-rich, if not most of them. If observations instead find a lack of ice-rich super- Earths it may suggest that planetesimal formation is far more efficient than expected well inside the snowline, or perhaps that pebbles in the inner refractory disk are as large as in the outer icy disk. Indeed, this would favor rapid growth in the inner disk, although it is at odds with the inferred conditions in the early solar system. This talk comes as the 2nd part of a series of papers, where the 1st talk will be presented by Dr. S. Jacobson about the formation of terrestrial planets and rocky super-Earths. The 3rd talk will be presented by Dr. B. Bitsch about the formation of gas giant planets.

Abstract

International audience; Infrared Space Observatory observations demonstrated that water (H2O) and other species like carbon monoxide (CO) are supplied in giant planet upper atmospheres by external sources: interplanetary dust particle, icy rings and/or satellites, large comet impacts. These sources have different spatio-temporal properties that we can use to discriminate them. At Saturn, stratospheric CO was probably deposited by an ancient comet impact. For water, the situation remains unclear, even if Enceladus and its water geysers are promising candidates. In this paper, we model altitude-latitude distributions of water in Saturn's stratosphere and compare them with Herschel PACS and HIFI observations to determine its source. Herschel observations have already enabled the detection of a water torus at the orbital distance of Enceladus. A fraction of this water is predicted to rain on Saturn. We test this prediction and compare it to other possible sources.

Abstract

International audience; Superchondritic Sm/Nd (Samarium/Neodymium) ratio has been evidenced in Earth's mantle rocks [1]. This observation is at odds with the canonical view of planetary accretion from chondritic building blocks, leading to chondritic ratios of lithophile (i.e. rock loving elements) and refractory elements in the silicate Earth. Here we evaluate the influence of collisional erosion during accretion on the budget of lithophile and refractory elements such as Sm and Nd. During the late stages of planetary accretion, planets grow by colliding with other embryos and a remnant planetesimals population. It has been suggested that the superchondritic Sm/Nd could have been produced by collisional striping of the Earth's early crust during its accretion. We quantitatively constrain the amount of eroded mass during the late-stage growth of Earth analogs using a combination of analytical modeling [2] and N-body numerical simulations [3]. Our model takes into account the distribution of impactors and their evolving compositions during accretion. The effect of changing accretion scenarios is also studied (e.g. with or without a Grand-Tack). The final Sm/Nd ratio of the bulk silicate Earth is determined under 3 sets of assumptions: (1) The mantle and crust fully reequilibrate after each impact; (2) The accreted material merges with the crust only and the mantle does not reequilibrate with the crust (3) an intermediate case that depends on the size of the impactors. We show that planetesimal impacts play a dominant role in determining Earth's Sm/Nd ratio due to the efficiency of crustal erosion. This work has implications for understanding Earth's accretion history. [1] Boyet and Carlson, 2005. Science 309, 576-581 [2] Svetsov, 2011.

Abstract

International audience; Galactic Open Clusters (OCs) are crucial to investigate the formation and evolution of the Galactic disc. However, complete information is available for only 5% of the 2100 OCs in the Milky Way listed in the literature. Therefore, OCs are main targets in space missions (Gaia, Kepler), and in large ground-based spectroscopic surveys. However, these ground-based surveys are mainly sampling the Southern hemisphere OCs (Gaia-ESO survey, GALAH), or do not have an specific program for homogeneously sample OCs (APOGEE). The Open Clusters Chemical Abundance from Spanish Observatory survey (OCCASO) aims to complement these surveys obtaining detailed abundances for more than 20 chemical species in around 30 Northern OCs (Casamiquela et al, 2016 MNRAS 458, 3150). The advent of Gaia Data Release 2 (DR2, Gaia Collaboration 2018, arXiv:1804.09365) has allowed a redetermination of the membership and of the mean proper motions and parallaxes for all known clusters (Cantat-Gaudin et al, arXiv:1805.08726). Using these data, we have revisited the membership of our observed stars and obtained mean parameters for all our OCCASO OCs. Gaia DR2 mean parallaxes and proper motions and OCCASO radial velocities have been combined to obtain 3D spatial velocities and peculiar velocities with respect to the RSR. The results significantly differ from our previous calculations due to the differences with previous proper motions studies. The orbits of the OCs have been calculated using a gravitational potential of the Galaxy with two spirals arms and no central bar (Pichardo et al 2003, ApJ 582, 230). The assumed mass of the arms is 5% of the mass disc. The arms have a pitch angle of 12 deg and a pattern speed of 30 km/s/kpc. All OCs show velocities and orbits typical of the disc.

Abstract

International audience; Sulfur is of fundamental importance in a wide variety of phenomena such as life on Earth. This element is one of the most abundant elements in space S/H ˜ 1.3×10^{-5}, but sulfuratted molecules are not as abundant as expected, thus a better understanding of sulfur chemistry is needed. We study and model the abundance of H_{2}S in two prototypical dark clouds, TMC1 and Barnard 1, to shed light on the physical and chemical processes involved in H_{2}S creation and destruction. Our observations are consistent with a PDR model in which H_{2}S is formed in grain mantles and released to gas phase via photodesorption. We cannot discard the contribution of other desorption processes, such as chemical desorption and/or grain-grain collisions, to enhance the H_2S abundance.

Abstract

International audience; Cyanamide (NH _{2}CN) is thought to be an important pre-biotic molecule, as it is converted to urea in liquid water (Kilpatrick 1947). Despite being detected in external galaxies (Martín et al. 2006; Aladro et al. 2011), NH _{2}CN has only previously been detected twice in the Milky Way, in Sgr B2 (Turner et al. 1975) and Orion KL (White et al. 2003). Here we report the first detection of NH _{2}CN surrounding two solar-type protostars, using data from the Atacama Large Millimeter/submillimeter Array Protostellar Interferometric Line Survey (PILS) of IRAS 16293-2422 B and observations of NGC1333 IRAS2A taken with the IRAM Plateau de Bure Interferometer. Towards IRAS 16293B, we also detect the deuterated and ^{13}C isotopologues of NH _{2}CN, constituting the first interstellar detection of NHDCN. LTE analysis shows that the deuteration of cyanamide (˜ 1.7%) is similar to that of formamide (NH _{2}CHO), perhaps suggesting a common molecular precursor to both. The NH _{2}CN/NH _{2}CHO abundance ratio varies between the sources, being 0.2 for IRAS 16293-2422B and ˜ 0.02 for IRAS2A. These values are comparable to observed values for Sgr B2. We use the three-phase chemical kinetics model MAGICKAL to investigate the formation and destruction of this molecule. Production of NH _{2}CN on the surface of grains through the combination of NH _{2} and CN radicals was added to our network, and it is demonstrated that our model can reproduce observed gas-phase abundances of NH _{2}CN, depending on the choice of the gas-phase density. The NH _{2}CN/NH _{2}CHO abundance ratio is still too low however, which is perhaps related to overproduction of NH _{2}CHO. [1] Kilpatrick, M. L. 1947, J. Am. Chem.

Abstract

International audience; Solar UV radiation is a major source of energy for initiating chemical evolution towards complex organic structures, but it can also photo-dissociate even the most complex molecules. Thus, solar UV can erase the organic traces of past life at the surface of planets, such as Mars, destroy organic molecules present on meteorites and micrometeorites, influence the production of distributed sources in comets or initiate chemistry in Titan's atmosphere. In the interstellar medium, the UV radiation field emitted by stars in the galaxy is also responsible for the chemical evolution and the extraordinary diversity of organic molecules detected. PSS (Photochemistry on the Space Station) was a Low Earth Orbit (LEO) experiment, implemented from mid-2014 to early 2016 on the EXPOSE-R2 platform outside the International Space Station. Its goal was to improve our knowledge about the chemical nature and evolution of organic molecules with astrobiological implications in space environments. It was a new step in a series of experiments conducted outside the MIR space station, in the ESA BIOPAN and previous EXPOSE facilities. In PSS, both vented and sealed cells were used allowing exposure of both solid and gaseous samples. Five kinds of experiments was carried out exposing molecules related to different environmental factors of astrobiological significance: the interstellar medium, comets & meteorites, Titan, Mars, as well as a set of samples to test the stability of biochips in space. In this talk we will describe the PSS experiment and focus on some results related to the stability of some prebioticaly relevant compounds such as glycine, the simplest amino acid, and nucleobases such as uracil, guanine and adenine. These molecules were both exposed in Low Earth Orbit and studied in the laboratory in order to derive their photochemical lifetime if they are ejected from comets on dust particles and orbit around the Sun before reaching the Earth as micrometeorites. The results can lead to better understand the contribution of cometary particles in the establishment of an organic reservoir on primitive Earth.

Due to launch in May 2022 and arrival at Jupiter in October 2029, it will make detailed observations of the Jovian system, with a special focus on the planet itself, its giant magnetosphere, and the three icy moons: Ganymede, Callisto and Europa. The current mission baseline assumes a Jupiter tour of almost three years including two close flybys of Europa, fifteen flybys of Ganymede, and twelve flybys of Callisto, together with a high inclination phase of six months in order to characterize Jupiter high latitudes. In August 2032, JUICE will then orbit Ganymede for at least ten months, down to an altitude of 500km. The first goal of JUICE is to to characterize the conditions that might have led to the emergence of habitable environments among the Jovian satellites. Ganymede is a high-priority target as it provides a unique laboratory for analyzing the nature, evolution and habitability of icy worlds, including the characteristics of subsurface oceans, and its unique magnetosphere interaction with the Jovian magnetodisc. For Europa, the focus will be on recently active zones, while Callisto will be explored as a witness of the early Solar System. JUICE will also investigate the Jupiter system as an archetype of gas giants. The circulation, meteorology, chemistry and structure of the Jovian atmosphere will be studied from the cloud tops to the thermosphere and ionosphere. JUICE will also study the properties of the magnetodisc, and will analyse the coupling processes within the magnetosphere, ionosphere and thermosphere. The payload consists of 10 instruments plus a ground-based experiment (PRIDE) to better constrain the S/C position. A remote sensing package includes imaging (JANUS) and spectral-imaging capabilities from the UV to the sub-mm wavelengths (UVS, MAJIS, SWI). A geophysical package consists of a laser altimeter (GALA) and a radar sounder (RIME) for exploring the moons, and a radio science experiment (3GM) to sound the atmospheres and to determine the gravity fields. The in-situ package comprises a suite to study plasma and neutral gas environments (PEP) with remote sensing capabilities via energetic neutrals, a magnetometer (J-MAG) and a radio and plasma wave instrument (RPWI).

Abstract

International audience; In this work, we propose to use convolutional neural networks to detect contaminants in astronomical images. Each contaminant is treated in a one vs all fashion. Once trained, our network is able to detect various contaminants such as cosmic rays, hot and bad pixel defaults, persistence effects, satellite trails or fringe patterns in images of various field properties. The convolutional neural network is performing semantic segmentation: it can output a probability map, assigning to each pixel its probability to belong to the contaminant or the background class. Training and testing data have been gathered from real or simulated data.

Abstract

International audience; The study of the distribution of molecules in star forming regions helps to constrain the chemical models. The "mini-starburst" region associated to W43-MM1 includes a number of massive pre-stellar and proto-stellar cores candidates (e.g. tealt{Motte18, nony18}). It is an important sample of molecular cores at various evolutionary stages and moreover, it may contain the most massive cold core known in the whole Galaxy. We present high spatial resolution data from ALMA Cycle 2 and Cycle 3. We first introduce the technique we developed to substract automatically the continuum in large regions of molecular emission in order to study weak emission lines. Then we present the current state of our comparison of the molecular composition of the cores in W43-MM1, in particular between two high-mass cores of similar masses and sizes.

Abstract

International audience; Recently te{GattanoLambertLeBail2018}, a new classification of VLBI radio sources was built on the basis of their astrometric stability revealed by the use of the Allan standard deviation. In such a classification, sources are divided into three groups depending on the nature of the noise content in the astrometric time series. The global level of noise then orders sources within each group. In this proceedings, we present several strategies on the basis of this classification to realize celestial reference frames, i.e. for selecting the set of defining sources used to define the fundamental axes of the frame. This set of sources is usually constrained in the data reduction by a no-net rotation constraint. Using two tools developed to determine the stability of realized frames, one that analyzes the stability of the annual realizations of a given frame and another that analyzes the coherence of random sub-frames, we determine the best usage of this classification.

Abstract

International audience; Small molecules such as methanimine (CH_{2}NH), methylamine (CH _{3}NH _{2}), hydroxylamine (NH _{2}OH) and methyl isocyanate (CH _{3}NCO) belong to a select group of so-called prebiotic molecules that are thought to be at the basis of amino-acid and peptide-bond formation. On Earth, amino-acids are important building blocks of life, which through peptide bonds link with each other to form proteins. Recent ALMA observations have shown for the first time that CH _{2}NH and CH _{3}NCO are present around the low-mass, sun-like, protostar IRAS 16293-2422, showing that prebiotic building blocks could already have been present at the earliest formational stages of our own Solar System. [1][2] This work is conducted as part of the protostellar interferometric line survey, a broad band ALMA survey of the protostellar binary IRAS 16293-2422. The detections of CH _{2}NH and CH _{3}NCO rotational transitions are presented and integrated emission maps show their presence at Solar System scales ( 60 AU) around the protostar. Supporting solid-state laboratory data shows that CH _{3}NCO has its origin in the ice mantles of interstellar dust grains. Non-detections of NH _{2}OH and CH _{3}NH _{2} are used to constrain chemical pathways to interstellar amino-acid formation. Specifically, the abundance comparison of CH3NH2 between this low-mass protostar and the galactic centre source Sgr B2 shows that CH _{3}NH _{2} is depleted by at least 1-2 orders of magnitude in IRAS 16293-2422. This shows that around low-mass protostars CH _{2}NH might be a more relevant precursor to amino-acid formation than CH _{3}NH _{2}. [1] N.F.W. Ligterink et al., Month. Not. Roy. Astron.

Abstract

Context. We present the second Gaia data release, Gaia DR2, consisting of astrometry, photometry, radial velocities, and information on astrophysical parameters and variability, for sources brighter than magnitude 21. In addition epoch astrometry and photometry are provided for a modest sample of minor planets in the solar system. Aims. A summary of the contents of Gaia DR2 is presented, accompanied by a discussion on the differences with respect to Gaia DR1 and an overview of the main limitations which are still present in the survey. Recommendations are made on the responsible use of Gaia DR2 results. Methods. The raw data collected with the Gaia instruments during the first 22 months of the mission have been processed by the Gaia Data Processing and Analysis Consortium (DPAC) and turned into this second data release, which represents a major advance with respect to Gaia DR1 in terms of completeness, performance, and richness of the data products. Results. Gaia DR2 contains celestial positions and the apparent brightness in G for approximately 1.7 billion sources. For 1.3 billion of those sources, parallaxes and proper motions are in addition available. The sample of sources for which variability information is provided is expanded to 0.5 million stars. This data release contains four new elements: broad-band colour information in the form of the apparent brightness in the GBP (330-680 nm) and GRP (630-1050 nm) bands is available for 1.4 billion sources; median radial velocities for some 7 million sources are presented; for between 77 and 161 million sources estimates are provided of the stellar effective temperature, extinction, reddening, and radius and luminosity; and for a pre-selected list of 14 000 minor planets in the solar system epoch astrometry and photometry are presented. Finally, Gaia DR2 also represents a new materialisation of the celestial reference frame in the optical, the Gaia-CRF2, which is the first optical reference frame based solely on extragalactic sources. There are notable changes in the photometric system and the catalogue source list with respect to Gaia DR1, and we stress the need to consider the two data releases as independent. Conclusions. Gaia DR2 represents a major achievement for the Gaia mission, delivering on the long standing promise to provide parallaxes and proper motions for over 1 billion stars, and representing a first step in the availability of complementary radial velocity and source astrophysical information for a sample of stars in the Gaia survey which covers a very substantial fraction of the volume of our galaxy., 0, info:eu-repo/semantics/published

Abstract

These are the corresponding continuum data published in the paper. G328.2551-0.5321 has been observed with ALMA in Cycle 2, and the phase center was (RA,DE)J2000=(15:58:00.05, -53:57:57.8). We used 11 of the 7m antennas on the 2014 July 8 and 16, as well as 34 and 35 of the 12m antennas on 2015 May 3, and 2015 September 1, respectively. The 7m array observations are discussed in detail in Csengeri et al. (2017, Cat. J/A+A/600/L10). Here we also present the 12m array observations, for which the baseline range is 15m (17kλ) to 1574m (1809kλ). The total time on source was 7.4 minutes, and the system temperature (Tsys) varies between 120 and 200K. (2 data files).

Abstract

International audience; Previous simulations of planet formation utilizing single bodies including pebble accretion and planet migration imply that giant planets found in orbits exterior to 1 AU originate from the outer regions of protoplanetary discs (30-40 AU). Here we generalize such models to include the mutual gravity between a high number of growing planetary bodies. We investigate how the formation of planetary systems depends on the radial flux of pebbles through the protoplanetary disc and on the planet migration rate. Our N-body simulations confirm previous findings that giant planets originate from 30-40 AU when using nominal type-I and type-II migration rates and a pebble flux of approximately 100-200 Earth masses per Myr, enough to grow Jupiter within the lifetime of the solar nebula. However, planetary embryos growing interior to 30-40 AU also grow and migrate inwards to the inner system (r

Abstract

International audience; The dynamical origin of the inner solar system remains heavily debated. Models are constrained by the masses and orbits of the terrestrial planets, the very low mass and structure of the asteroid belt, and the architecture of the outer solar system. It is well-accepted that the late stage of terrestrial accretion is characterized by giant collisions among Mars-mass planetary "embryos". Two contrasting views exist regarding the state of the inner system at this stage. The first view assumes a smooth mass distribution of terrestrial bodies with up to a few Earth masses in solids in the asteroid region. To match the current belt in this view, models must deplete the asteroid region by a factor of 100-1000. The classical model systematically fails to reproduce the large Earth/Mars mass ratio and and tends to strand Mars-mass embryos in the belt, which is inconsistent with the present-day belt. New models have been built taking into account the fact that matching Mars' small mass requires a severe mass deficit beyond 1 au. The Grand-Tack model invokes a specific migration history of the giant planets to deplete Mars' feeding zone, to deplete and excite the asteroid belt, successfully matching constraints. Yet uncertainties in the giant planets' growth and migration histories have motivated alternative scenarios that do not require large scale radial migration. Another viable model invokes also an early dynamical instability in the giant planet's orbits to deplete the asteroid belt and Mars' feeding zone. In the second, contrasting view the asteroid belt region was already strongly mass depleted before the late phase of terrestrial accretion. The low-mass asteroid belt model starts with a belt a few times more massive than the current one and naturally produces good Mars analogs. The giant planets can subsequently excite the asteroids' orbits to the current observed levels in a way that is consistent with models of the dynamical evolution of the outer solar system. In this talk we will review these scenarios and discuss their implications and potential ways to distinguish them.

Abstract

International audience; We report the detection of H13CN, HCN and upper limits of HC15N in Neptune's atmosphere with our ALMA observations. These measurements will allow us to constrain the 12C/13C and 14N/15N Isotopic ratio in Neptune's stratosphere. Our observations -performed on April 30, 2016- used the ALMA interferometer to search in Neptune's atmosphere for HCN(4-3), H13CN(4-3) and HC15N(4-3) rotational lines at 354.505, 345.339, and 344.200 GHz, respectively. These measurements were obtained using about 41 antenna of the 12m array, despite the angular resolution of 0.6'' and Neptune's angular surface diameter was 2.24'', only disk-averaged measurements allowed to detect with sufficient signal-to-noise ratio the H13CN line, while only upper limits of HC15N were obtained. We will present the analysis of these observations, which will include i) the vertical profile of HCN, ii) the isotopic ratio of 12C/13C and 14N/15N and finally discuss the origin of HCN in Neptune's stratosphere.

Abstract

Context. The Gaia spacecraft of the European Space Agency (ESA) has been securing observations of solar system objects (SSOs) since the beginning of its operations. Data Release 2 (DR2) contains the observations of a selected sample of 14,099 SSOs. These asteroids have been already identified and have been numbered by the Minor Planet Center repository. Positions are provided for each Gaia observation at CCD level. As additional information, complementary to astrometry, the apparent brightness of SSOs in the unfiltered G band is also provided for selected observations. Aims. We explain the processing of SSO data, and describe the criteria we used to select the sample published in Gaia DR2. We then explore the data set to assess its quality. Methods. To exploit the main data product for the solar system in Gaia DR2, which is the epoch astrometry of asteroids, it is necessary to take into account the unusual properties of the uncertainty, as the position information is nearly one-dimensional. When this aspect is handled appropriately, an orbit fit can be obtained with post-fit residuals that are overall consistent with the a-priori error model that was used to define individual values of the astrometric uncertainty. The role of both random and systematic errors is described. The distribution of residuals allowed us to identify possible contaminants in the data set (such as stars). Photometry in the G band was compared to computed values from reference asteroid shapes and to the flux registered at the corresponding epochs by the red and blue photometers (RP and BP). Results. The overall astrometric performance is close to the expectations, with an optimal range of brightness G ∼ 12 - 17. In this range, the typical transit-level accuracy is well below 1 mas. For fainter asteroids, the growing photon noise deteriorates the performance. Asteroids brighter than G ∼ 12 are affected by a lower performance of the processing of their signals. The dramatic improvement brought by Gaia DR2 astrometry of SSOs is demonstrated by comparisons to the archive data and by preliminary tests on the detection of subtle non-gravitational effects., 0, info:eu-repo/semantics/published

Abstract

International audience; There are large variations in the stable isotope composition of the volatile elements hydrogen, nitrogen, and oxygen among the solar system bodies. The solar system solids are typically enriched in the rare heavy isotopes (D, 15N, 17O, 18O) compared to the Sun and Jupiter. To understand the origin of these isotopic anomalies, a cross-disciplinary link between the fields of astronomy, cosmochemistry, and solar system science is indispensable. However, establishing such as link is not straightforward, as astronomical observations mainly target the gas in star-forming regions, whereas the most pristine solar system materials are present in the form of meteorites and cometary ices. The ratio of the two stable nitrogen isotopes, 14N/15N, is a promising tool for linking results across the fields, as the nitrogen isotopic composition can be measured in star-forming regions and solar system bodies. The 14N/15N ratio should also be less prone to secondary alteration than the deuterium-to-hydrogen ratio.In this contribution, we will present spatially resolved measurements of the 14N/15N ratio around embedded protostars from IRAM observations and the Protostellar Interferometric Line Survey (PILS) with ALMA. First results on the nitrogen isotopic composition of comet 67P/Churyumov-Gerasimenko by Rosetta-ROSINA will also be presented, and we will explain how we are trying to link these data sets to gain insights into the origin of nitrogen in our solar system and beyond.

Abstract

International audience; Thousands of exoplanets have now been discovered with a huge range of masses, sizes and orbits: from rocky Earth-size planets to large gas giants grazing the surface of their host star. However, the essential nature of these exoplanets remains largely mysterious: there is no known, discernible pattern linking the presence, size, or orbital parameters of a planet to the nature of its parent star. We have little idea whether the chemistry of a planet is linked to its formation environment, or whether the type of host star drives the physics and chemistry of the planet's birth, and evolution. Progress with these science questions demands a large, unbiased spectroscopic survey of exoplanets. The ESA ARIEL M4 candidate mission has been conceived to conduct such a survey and to explore the nature of exoplanet atmospheres and interiors and, through this, the key factors affecting the formation and evolution of planetary systems.

Abstract

The asteroid belt contains less than a thousandth of Earth's mass and is radially segregated, with S-types dominating the inner belt and C-types the outer belt. It is generally assumed that the belt formed with far more mass and was later strongly depleted. Here we show that the present-day asteroid belt is consistent with having formed empty, without any planetesimals between Mars and Jupiter's present-day orbits. This is consistent with models in which drifting dust is concentrated into an isolated annulus of terrestrial planetesimals. Gravitational scattering during terrestrial planet formation causes radial spreading, transporting planetesimals from inside 1-1.5 AU out to the belt. Several times the total current mass in S-types is implanted, with a preference for the inner main belt. C-types are implanted from the outside, as the giant planets' gas accretion destabilizes nearby planetesimals and injects a fraction into the asteroid belt, preferentially in the outer main belt. These implantation mechanisms are simple byproducts of terrestrial- and giant planet formation. The asteroid belt may thus represent a repository for planetary leftovers that accreted across the Solar System but not in the belt itself., Published in Science Advances (this is authors' version).

Abstract

The early evolution of massive cluster progenitors is poorly understood. We investigate the fragmentation properties from 0.3 pc to 0.06 pc scales of a homogenous sample of infrared-quiet massive clumps within 4.5 kpc selected from the ATLASGAL survey. Using the ALMA 7m array we detect compact dust continuum emission towards all targets, and find that fragmentation, at these scales, is limited. The mass distribution of the fragments uncovers a large fraction of cores above 40 $M_\odot$, corresponding to massive dense cores (MDCs) with masses up to ~400 $M_\odot$. 77 % of the clumps contain at most 3 MDCs per clump, and we also reveal single clumps/MDCs. The most massive cores are formed within the more massive clumps, and a high concentration of mass on small scales reveals a high core formation efficiency. The mass of MDCs highly exceeds the local thermal Jeans-mass, and observational evidence is lacking for a sufficiently high level of turbulence or strong enough magnetic fields to keep the most massive MDCs in equilibrium. If already collapsing, the observed fragmentation properties with a high core formation efficiency are consistent with the collapse setting in at parsec scales., accepted by A&A Letters

Abstract

The data are provided as two separate FITS files, one for B1b-N and one for B1b-S. The data have been obtained with ALMA in continuum mode. Four continuum basebands with 2 GHz bandwidth, 128 channels each have been combined. Central sky frequencies on each band are 2336.5 and 338.4GHz in the lower side band and 3548.5 and 350.5GHz in the upper side band. The images have been produced by combining two observing sessions in two ALMA configurations C36-7 and C40-4, for a total of 30 minutes on source. The data processing and calibration is described in the article. The image units are Jy/beam. (2 data files).

Abstract

Table 5 : Physical parameters for the 566 molecular clouds identified through the IRAM 30m CO J=2-1 survey of the star forming disk of M33. For each cloud the cloud type and the following properties are listed: celestial coordinates, galactocentric radius, cloud deconvolved effective radius and its uncertainty, CO(2-1) line velocity dispersion from CPROPS and its uncertainty, line velocity dispersion from a Gaussian fit, CO luminous mass and its uncertainty, and virial mass from a Gaussian fit. In the last column the identification number of the young stellar cluster candidates associated with the molecular cloud are listed. Notes: We identify up to four young stellar cluster candidates (YSCCs) associated with each molecular cloud and we list them according to the identification number of Sharma et al. (2011, Cat. J/A+A/545/A96) given also in Table 6. Table 6 : Physical parameters for the 630 young stellar cluster candidates identified via their mid-infrared emission in the star forming disk of M33. For each YSCC we list the type of source, the identified number of the molecular clouds associated with it (if any) and the corresponding cloud classes. In addition, for each YSCC we give the celestial coordinates, the bolometric, total infrared, FUV and Halpha luminosities, the estimated mass and age, the visual extinction, the galactocentric radius, the source size, and its flux at 24μm.

Abstract

International audience; The years 2016-2017 have been extremely fruitful in discoveries of interesting nearby Earth-size exoplanets. The detections of Proxima Cen b and TRAPPIST-1 planets are major discoveries mostly because these - very likely rocky - planets are the best candidates for future atmospheric characterization by transit spectroscopy, direct imaging, or thermal phase curve with the forthcoming ground (e.g. E-ELT) or space-based (e.g. JWST) astronomical observatories. We explore the possible climates of these planets and produce observational constraints that can be used to discriminate between all the possible atmospheric states of the planets.

Abstract

International audience; Over the next decade, the IVS is on the cusp of dramatic changes transitioning from using large, slow moving antennas observing at S/X (``legacy'' systems) to using small, fast antennas with broad-band receivers, the so-called VGOS systems. Never has there been a time when so many antennas specifically designed for geodetic VLBI are scheduled to come on line in such a short period. VGOS observing will change all aspects of VLBI, from scheduling, to correlation, to observing strategy, to analysis. Compared to current observing, a typical VGOS session will have 1-2 orders of magnitude more data. In this strategic plan we outline some of the operational concepts of VGOS observing, our goals for data accuracy and latency, and some of the challenges and issues we will face during this transition.

Abstract

International audience; As chartered by the Science Definition Team, the Mars 2020 mission addresses four primary objectives: A. Characterize the processes that formed and modified the geologic record within an astrobiologically relevant ancient environment, B. Perform astrobiologically relevant investigations to determine habitability, search for materials with biosignature presentation potential, and search for evidence of past life, C. Assemble a returnable cache of samples and D. Contribute to preparation for human exploration of Mars. The SuperCam instrument, selected for the Mars 2020 rover, as a suite of four instruments, provides nested and co-aligned remote investigations: Laser Induced Breakdown Spectroscopy (LIBS), Raman spectroscopy and time-resolved fluorescence (TRF), visible and near-infrared spectroscopy (VISIR), and high resolution color imaging (RMI). SuperCam appeals broadly to the four Mars 2020 objectives.In detail, SuperCam will perform:1. Microscale mineral identification by combining LIBS elemental and VISIR mineralogical spectroscopies, especially targeting secondary minerals2. Determine the sedimental stratigraphy through color imaging and LIBS and VISIR spectroscopy3. Search for organics and bio-signatures with LIBS and Raman spectroscopy4. Quantify the volatile content of the rocks by LIBS spectroscopy to determine the degree of aquaeous alteration5. Characterize the texture of the rocks by color imaging to determine their alteration processes6. Characterize the rocks' coatings by LIBS spectroscopy7. Characterize the soil and its potential for biosignature preservation8. Monitor the odd-oxygen atmospheric chemistry.To meet these goals SuperCam will perform LIBS spectroscopy on 0.5 mm spot up to 7-meter distance, perform Raman and time-resolved fluoresence up to 12-m distance with a 0.8 mrad angular resolution, a 100 ns time gating in the 534-850 nm spectral range, acquire VISIR spectra in the range 0.4-0.85 μm with a resolution of 0.35 nm, and in the IR range over 1.3-2.6 μm, rich in mineral signatures, with a resolution of 20 nm, and provide RGB images with an angular resolution of 40 μrad over a FOV of 20 mrad.We will present the science performances of SuperCam and the forecasted operation plans.

Abstract

International audience; The Atmospheric Remote-Sensing Infrared Exoplanet Large-survey (ARIEL) is one of the three candidate missions selected by the European Space Agency (ESA) for its next medium-class science mission due for launch in 2026. The goal of the ARIEL mission is to investigate the atmospheres of several hundreds planets orbiting distant stars in order to address the fundamental questions on how planetary systems form and evolve.During its four (with a potential extension to six) years mission ARIEL will observe 500+ exoplanets in the visible and the infrared with its meter-class telescope in L2. ARIEL targets will include Jupiter- and Neptune-size down to super-Earth and Earth-size around different types of stars. The main focus of the mission will be on hot and warm planets orbiting very close to their star, as they represent a natural laboratory in which to study the chemistry and formation of exoplanets. In cooler planets, different gases separate out through condensation and sinking into distinct cloud layers. The scorching heat experienced by hot exoplanets overrides these processes and keeps all molecular species circulating throughout the atmosphere.The ARIEL mission concept has been developed by a consortium of more than 50 institutes from 12 countries, which include UK, France, Italy, Germany, the Netherlands, Poland, Spain, Belgium, Austria, Denmark, Ireland and Portugal. The analysis of ARIEL spectra and photometric data will allow to extract the chemical fingerprints of gases and condensates in the planets' atmospheres, including the elemental composition for the most favorable targets. It will also enable the study of thermal and scattering properties of the atmosphere as the planet orbit around the star.ARIEL will have an open data policy, enabling rapid access by the general community to the high-quality exoplanet spectra that the core survey will deliver.

Abstract

The chemical tagging technique proposed by Freeman & Bland-Hawthorn (2002) is based on the idea that stars formed from the same molecular cloud should share the same chemical signature. Thus, using only the chemical composition of stars we should be able to re-group the ones that once belonged to the same stellar aggregate. In Blanco-Cuaresma et al. (2015), we tested the technique on open cluster stars using iSpec (Blanco-Cuaresma et al. 2014a), we demonstrated their chemical homogeneity but we found that the 14 studied elements lead to chemical signatures too similar to reliably distinguish stars from different clusters. This represents a challenge to the technique and a new question was open: Could the inclusion of other elements help to better distinguish stars from different aggregates? With an updated and improved version of iSpec, we derived abundances for 28 elements using spectra from HARPS, UVES and NARVAL archives for the open clusters M67 and IC4651, and we found that the chemical signatures of both clusters are very similar., To appear in SF2A-2016: Proceedings of the Annual meeting of the French Society of Astronomy and Astrophysics

Abstract

International audience; The COSMIC-DANCE project is an observational program aiming at understanding the origin and evolution of ultracool objects by measuring the mass function and internal dynamics of young nearby associations down to the fragmentation limit. The least massive members of young nearby associations are identified using modern statistical methods in a multi-dimensional space made of optical and infrared luminosities and colors and proper motions. The photometry and astrometry are obtained by combining ground and in some case space based archival observations with new observations, covering between one and two decades.
