Abstract

ABSTRACT Infrared (IR) spectra provide a rich amount of information concerning chemical composition, lattice structure, size and shape of circumstellar dust. Accurate reference data are then required for the analysis of the various detected components. This study provides the IR characterization of one of the most frequently observed compounds, MgSiO3 ortho-enstatite, and shows that IR experiments and ab initio techniques can be used synergically to obtain high-quality data concerning crystalline materials. The IR reflectance spectrum of synthetic ortho-enstatite was collected and compared to ab initio results (Gaussian-type basis set, PBE0 hybrid density functional theory (DFT) functional). An excellent agreement is observed both for vibrational frequencies (ν) and intensities, the latter estimated through the oscillator strength. The mean absolute difference between experimental and calculated ν is of the order of 7-8 cm−1 (43 out of 65 peaks differ by less than 10 cm−1, only four peaks differ by 15-19 cm−1). The static dielectric tensor and its components (electronic and ionic contributions) were measured and compared to calculated data: differences are in the 2-5 per cent range. [ABSTRACT FROM AUTHOR]

291. First observations of CO 2 absorption spectra recorded in 2005 using an airship-borne FTS (GOSAT TANSO–FTS BBM) in the SWIR spectral region.

Abstract

This article describes the results of a field experiment performed to confirm the feasibility of measuring the solar spectra absorbed by carbon dioxide (CO2) using a short wavelength infrared Fourier transform spectrometer (SWIR-FTS) installed onboard an airship. These airship-borne observations, conducted on 7 April 2005, represent the first aircraft-borne spectroscopic experiment on greenhouse gases (GHGs) in Japan and were performed as part of the Greenhouse Gases Observing Satellite (GOSAT) project. To develop and demonstrate an effective retrieval algorithm to derive CO2 column amounts from spectroscopic observations, ground-surface scattered solar absorption spectra were observed by SWIR-FTS installed onboard the airship. This instrument is a breadboard model (BBM) of the Thermal and Near-infrared Sensor for Carbon Observation (TANSO) of GOSAT, which was successfully launched on 23 January 2009. The spectra of CO2 observed using the BBM were compared with the simulated spectra calculated by a radiative transfer code based on airship-borne in situ measurement data, which were obtained at the time of FTS measurements. The two sets of spectra are in agreement within 5%, and we identified solutions to several technical problems related to the FTS instrument, thereby improving the signal-to-noise ratio (SNR).

293. A circumstellar disk associated with a massive protostellar object.

Abstract

The formation process for stars with masses several times that of the Sun is still unclear. The two main theories are mergers of several low-mass young stellar objects, which requires a high stellar density, or mass accretion from circumstellar disks in the same way as low-mass stars are formed, accompanied by outflows during the process of gravitational infall. Although a number of disks have been discovered around low- and intermediate-mass young stellar objects, the presence of disks around massive young stellar objects is still uncertain and the mass of the disk system detected around one such object, M17, is disputed. Here we report near-infrared imaging polarimetry that reveals an outflow/disk system around the Becklin–Neugebauer protostellar object, which has a mass of at least seven solar masses (M\cirċ). This strongly supports the theory that stars with masses of at least 7M\cirċ form in the same way as lower mass stars. [ABSTRACT FROM AUTHOR]

297. Near-Infrared Imaging of Late Type Stars Using CIAO on the Subaru Telescope.

Author

Brandner, Wolfgang, Kasper, Markus E., Murakawa, Koji, and Suto, Hiroshi

Abstract

We have manufactured a near infrared camera named coronagraphic imager with adaptive optics; CIAO mounted on the Cassegrain focus of the Subaru 8m telescope. CIAO is a high resolution and high dynamic range camera optimized for detection of faint objects around bright source. Combining with a 36 element AO, CIAO can produce nearly diffraction limited image at K band. Using CIAO's coronagraph, the limiting magnitude differences at 1" separation from the central star of 8.4 mag at 5σ and 10 minutes integration time can be obtained. CIAO currently has a half-wave plate and a wire-grid polarizer for measurement of linear polarization at JHK band. An interesting result of imaging-polarimetry of a C-rich late type star IRC+10216 will be presented. [ABSTRACT FROM AUTHOR]

298. Updated level-1 processing after two-years operation of TANSO-FTS

Author

Suto, Hiroshi, Kuze, Akihiko, Shiomi, Kei, and Nakajima, Masakatsu

Abstract

To monitor the global column concentration of carbon dioxide (CO2) and methane (CH4) from space, the Greenhouse gases Observing SATellite (GOSAT) was launched on January 23, 2009, and has started the operational observation. Thermal and Near Infrared Sensor for Carbon Observation- Fourier Transform Spectrometer (TANSO-FTS) has been continuously measuring CO2and CH4distributions globally every three days, and data distribution to the public started from Feb. 16, 2010. During two years operational periods, the radiometric, geometric and spectroscopic characterizations of TANSO have been continuously conducted with updating the Level-1 processing algorithm. To make a precise spectroscopic observation, correction algorithms were newly developed, demonstrated and installed on operational processing. Two major corrections are discussed. One is correction of the scan-speed instability caused by microvibration from satellite. Through the on-orbit data analysis, degrading spectroscopic accuracy caused by periodically micro-vibrations was found, and these distortion effects were compensated with applying the re-sampling technique for interferogram. The other is non-linearity correction in the electronics. In this presentation, the detail of on-orbit characteristics and the current status of Level-1procesing for TANSO will be presented.

299. Mountaintop observation of CO_2 absorption spectra using a short wavelength infrared Fourier transform spectrometer

Author

Yoshida, Yukio, Oguma, Hiroyuki, Morino, Isamu, Suto, Hiroshi, Kuze, Akihiko, and Yokota, Tatsuya

Abstract

The absorption spectra of surface-scattered solar radiation were measured from the top of Mount Tsukuba (altitude 833 m) in the short wavelength infrared region using a Fourier transform spectrometer (FTS). The FTS used in this experiment was the breadboard model of the FTS on the Greenhouse Gases Observing Satellite, which was launched on 23 January 2009. In situ measurement of carbon dioxide (CO_2) from a Cessna airplane was performed simultaneously with the FTS observation. The CO_2 column abundances were retrieved from the observed spectra under the assumption of the absence of aerosol. The retrieved CO_2 column abundances over a few minutes dispersed within 1%. The remaining bias was considered to be caused by the no-aerosol assumption.

300. Thermal and near infrared sensor for carbon observation Fourier-transform spectrometer on the Greenhouse Gases Observing Satellite for greenhouse gases monitoring

Author

Kuze, Akihiko, Suto, Hiroshi, Nakajima, Masakatsu, and Hamazaki, Takashi

Abstract

The Greenhouse Gases Observing Satellite (GOSAT) monitors carbon dioxide (CO_2) and methane (CH_4) globally from space using two instruments. The Thermal and Near Infrared Sensor for Carbon Observation Fourier-Transform Spectrometer (TANSO-FTS) detects gas absorption spectra of the solar short wave infrared (SWIR) reflected on the Earth's surface as well as of the thermal infrared radiated from the ground and the atmosphere. TANSO-FTS is capable of detecting three narrow bands (0.76, 1.6, and 2.0 μm) and a wide band (5.5-14.3 μm) with 0.2 cm^−1 spectral resolution (interval). The TANSO Cloud and Aerosol Imager (TANSO-CAI) is an ultraviolet (UV), visible, near infrared, and SWIR radiometer designed to detect cloud and aerosol interference and to provide the data for their correction. GOSAT is placed in a sun-synchronous orbit 666 km at 13:00 local time, with an inclination angle of 98 °. A brief overview of the GOSAT project, scientific requirements, instrument designs, hardware performance, on-orbit operation, and data processing is provided.
