Abstract

Rossby waves are a pervasive feature of the large-scale motions of the Earth’s atmosphere and oceans. These waves (also known as planetary waves and r-modes) also play an important role in the large-scale dynamics of different astrophysical objects such as the solar atmosphere and interior, astrophysical discs, rapidly rotating stars, planetary and exoplanetary atmospheres. This paper provides a review of theoretical and observational aspects of Rossby waves on different spatial and temporal scales in various astrophysical settings. The physical role played by Rossby-type waves and associated instabilities is discussed in the context of solar and stellar magnetic activity, angular momentum transport in astrophysical discs, planet formation, and other astrophysical processes. Possible directions of future research in theoretical and observational aspects of astrophysical Rossby waves are outlined.

Abstract

The Solar Dynamics Observatory/Helioseismic and Magnetic Imager (SDO/HMI) filtergrams, taken at six wavelengths around the Fe I 6173.3 {\AA} line, contain information about the line-of-sight velocity over a range of heights in the solar atmosphere. Multi-height velocity inferences from these observations can be exploited to study wave motions and energy transport in the atmosphere. Using realistic convection simulation datasets provided by the STAGGER and MURaM codes, we generate synthetic filtergrams and explore several methods for estimating Dopplergrams. We investigate at which height each synthetic Dopplergram correlates most strongly with the vertical velocity in the model atmospheres. On the basis of the investigation, we propose two Dopplergrams other than the standard HMI-algorithm Dopplergram produced from HMI filtergrams: a line-center Dopplergram and an average-wing Dopplergram. These two Dopplergrams correlate most strongly with vertical velocities at the heights of 30 - 40 km above (line-center) and 30 - 40 km below (average-wing) the effective height of the HMI-algorithm Dopplergram. Therefore, we can obtain velocity information from two layers separated by about a half of a scale height in the atmosphere, at best. The phase shifts between these multi-height Dopplergrams from observational data as well as those from the simulated data are also consistent with the height-difference estimates in the frequency range above the photospheric acoustic cutoff frequency., Comment: accepted for publication in Solar Physics

Abstract

Matière Nucléaire; The decay out of the πh 11/2νh 11/2 band to the known low-energy levels in 132La was studied using the reaction 100Mo + 36S at 160 MeV beam energy. The low-energy level scheme has been further developed and unambiguous spin and parity values have been assigned to the levels connecting the band to the 6- isomeric state. According to the new level scheme the spins in the πh 11/2νh 11/2 band are shifted up by one unit compared to the earlier tentative experimental values. The obtained new spins prove the existence of signature inversion in 132La and give further support to the spin assignments made for the πh 11/2νh 11/2 bands in the neighbouring odd-odd La isotopes from level energy systematics.

Abstract

A high-spin level structure of the nucleus 154Tm has been established for the first time up to 6.14 MeV. The 118Sn + 40Ca reaction at 205 MeV associated with the recoil shadow method was used to identify the I π = (19)+ isomeric state at 2.74 MeV. In-beam γ-ray and conversion electron spectroscopy have been applied on the 144Sm(14N, 4n)154Tm reaction at 95 MeV to build the level scheme. The level structure of 154Tm is compared to other structures observed in N = 85 neighbouring nuclei. (Springer)

Abstract

The high-spin level structure of the 153Er nucleus has been reinvestigated by in-beam %-ray and electron spectroscopy with (14N,pxn) reaction. Excitation energies, spin and parity assignments are unambiguously established for the two lowest isomers T1/2 ­ 380 ns and T1/2\simeq 10 ns. The characteristics of the third one (T1/2 ­ 250 ns) at 5.2 MeV are still questionable but its main decay modes are better known. An extension of the level scheme is proposed up to 8.4 MeV.Experimental results have been discussed in terms of shell model multiplets and compared with the other structures observed in N=85 neighbouring nuclei.

Abstract

High spin states of 101Rh have been populated using the reaction 70Zn+36S at 130 MeV. γ-rays were detected with the EUROGAM2 array. New high-spin bands have been observed in this nucleus up to 45/2−, 57/2− and 65/2+ states. They have been interpreted using the Nilsson-Strutinsky cranking formalism as terminating configurations. Two of the bands were observed up to the predicted terminating states which are built up from g9/2 protons as well as d5/2, g7/2 and h11/2 neutrons relative to a 90Zr core.

Abstract

Quantitative helio- and asteroseismology require very precise measurements of the frequencies, amplitudes, and lifetimes of the global modes of stellar oscillation. It is common knowledge that the precision of these measurements depends on the total length (T), quality, and completeness of the observations. Except in a few simple cases, the effect of gaps in the data on measurement precision is poorly understood, in particular in Fourier space where the convolution of the observable with the observation window introduces correlations between different frequencies. Here we describe and implement a rather general method to retrieve maximum likelihood estimates of the oscillation parameters, taking into account the proper statistics of the observations. Our fitting method applies in complex Fourier space and exploits the phase information. We consider both solar-like stochastic oscillations and long-lived harmonic oscillations, plus random noise. Using numerical simulations, we demonstrate the existence of cases for which our improved fitting method is less biased and has a greater precision than when the frequency correlations are ignored. This is especially true of low signal-to-noise solar-like oscillations. For example, we discuss a case where the precision on the mode frequency estimate is increased by a factor of five, for a duty cycle of 15%. In the case of long-lived sinusoidal oscillations, a proper treatment of the frequency correlations does not provide any significant improvement; nevertheless we confirm that the mode frequency can be measured from gapped data at a much better precision than the 1/T Rayleigh resolution., Comment: Accepted for publication in Solar Physics Topical Issue "Helioseismology, Asteroseismology, and MHD Connections"

Abstract

Published online 7 August 2007; Low-spin states of $^{182}Ir$ were populated through the $\beta^+/EC$ decay of $^{182}Pt$. Two strong $E2$ transitions were observed for the first time: a 25.7keV transition in $^{182}Ir$ and a 34.0keV transition in Re of probable mass A = 178. Spin and parity, $I^\pi = 3^+$, are firmly assigned to the $^{182}Ir$ ground state (g.s.). For the excited states, the parity is established and the spin determined or restricted. These assignments support most of the interpretations of the level structure previously suggested. The systematics for the known $5^+ \to 3^+$ transitions in $\pi h_{9/2} \bigotimes ν 1/2^-[521]$ bands is presented. Using a semi-microscopic two-quasiparticle axial-rotor coupling model, particle configurations have been attributed or suggested for most of the coupled states lying at low energy in $^{182}Ir$.

Abstract

Flows in the upper convection zone are measured by helioseismology on a wide variety of scales. These include differential rotation and meridional circulation, local flows around complexes of magnetic activity and sunspots, and convective flows. The temporal evolution of flows through cycle 23 reveals connections between mass motions in the solar interior and the large-scale characteristics of the magnetic cycle. Here I summarize the latest observations and their implications. Observations from local helioseismology suggest that subsurface flows around active regions introduce a solar-cycle variation in the meridional circulation.

Abstract

The variation of rotation with latitude is poorly known on stars other than the Sun. Several indirect techniques, photometric and spectroscopic, have been used to search for departure from rigid rotation for sufficiently fast rotators. Here we investigate the possibility of measuring stellar differential rotation for solar-type stars through asteroseismology. Rotationally split frequencies of global oscillation provide information about rotation at different latitudes depending on the azimuthal order, m, of the mode of pulsation. We present a method to estimate differential rotation based on the realization that the m =± 1a ndm =± 2 components of quadrupole oscillations can be observed simultaneously in asteroseismology. Rotational frequency splittings can be inverted to provide an estimate of the difference in stellar angular velocity between the equator and 45 ◦ latitude. The precision of the method, assessed through Monte Carlo simulations, depends on the value of the mean rotation and on the inclination angle between the rotation axis and the line of sight.

Abstract

An investigation of low-lying energy levels of 130Pr and 130Ce has been made via β-decay. The radioactive parent nuclei were produced via 94,96Mo + 40Ca reactions at 6.8 MeV/nucleon and transported by a He-jet system. Gamma-γ-t, γ-X-t, γ-e--t coincidence measurements were performed. Internal conversion coefficients have been measured with a magnetic spectrometer. The new β-decay half-life of 130Nd has been determined to be 21(3) s. A partial level scheme of 130Pr at low-spin has been constructed. The β-decay of 130Pr to 130Ce suggests the existence of three β-instable isomeric states in 130Pr, while only one half-life T 1/2 = 40(4) s has been measured. Based on the present work and low-lying excited states in neighbouring odd-mass nuclei, the spins and parities of isomeric states in 130Pr are proposed to be 2+, (4,5)+ and (7,8±). The ground state in 130Pr is still undetermined.

Abstract

Low-spin states of 184Au have been studied using the β+/EC decay of 184Hg. γ-ray and conversion-electron singles spectra were recorded with 184Hg mass-separated sources. For γ-γ-t and X-γ-t coincidence measurements, mercury nuclei were produced in the 148Sm + 40Ar reaction and transported by a He-jet system. The electron spectra were recorded from 184Hg sources produced at ISOLDE. A level scheme of 184Au including 48 transitions is proposed. The experimental results are interpreted in the frame of a semi-microscopic axial-rotor-plus-two-quasiparticle model developed in the context of the HF+BCS approximation.

Abstract

Surface gravity waves have been used to probe flows in the two megameters beneath the photosphere using the techniques of time-distance helioseismology. The results suggest that supergranule velocities are smaller than at the surface. The outward flow outside a sunspot penumbra (the moat) is observed, as is an inward flow in the region beyond the moat.

Abstract

High spin states in 127Ba have been investigated with the fusion–evaporation reaction 96Zr(36S,5n)127Ba at a beam energy of 150 MeV with the GASP-spectrometer at INFN in Legnaro, Italy. The level scheme could be extended to high spins resulting in the observation of five-quasiparticle states. Altogether 15 band structures were placed in the level scheme.

Abstract

Nilsson-Strutinsky cranking calculations on A ≥ 100 Ru and Pd nuclei suggest that, contrary to other mass regions, it should be possible to follow the ground state rotational bands to their termination at spins just above I = 30ℏ and then also to observe other bands which terminate at higher spins.

Abstract

The219Ra levels, fed by the α-decay of223Th, have been studied by anα−γ coincidence experiment. AK=1/2+ band, based on the 7/2+ ground state, with a large decoupling parameter a=−5.5 is proposed. Three levels with spins 5/2, 9/2, 7/2 and lowα-hindrance factors around 140 keV, can be considered as members of aK=5/2+ band, perturbed by the Coriolis coupling of configurations arising from theg9/2 shell. TheseK =1/2+ and 5/2+ orbitals are expected forN=131 in the reflection asymmetry model with ɛ2≃ɛ3−0.1. How-ever no evidence was found for the corresponding negative parity bands in this transitional nucleus.

Abstract

High spin states of 100Rh have been populated using the reaction 70Zn+36S at 130 MeV. γ-rays were detected with the EUROGAM2 array. The level structure of 100Rh has been extended up to 14.41 MeV excitation energy. Several band structures are observed. A band based on a Iπ=8− state is developed up to the Iπ=24− level. It is assigned as the πg 9/2 −5νh 11/2 configuration.
