Dust science with SPICA mid-infrared camera and spectrometers (MCS)

Itsuki Sakon Takashi Onaka Hirokazu Kataza Takehiko Wada Yuki Sarugaku Hideo Matsuhara Takao Nakagawa Naoto Kobayashi Ciska Kemper Youichi Ohyama Toshio Matsumoto Ji Yeon Seok

Proceedings of Science 2013年

Mid-Infrared Camera and Spectrometers (MCS) is one of the Focal-Plane Instruments proposed for the SPICA mission in the pre-project phase. SPICA MCS is equipped with two spectrometers with different spectral resolution powers (R=Λ/δΛ); medium-reso...

UV/OPTICAL/IR SPACE TELESCOPES AND INSTRUMENTS: INNOVATIVE TECHNOLOGIES AND CONCEPTS VI 8860 2013年

An image slicer is highly in demand for an integral field unit (IFU) spectrograph of the next generation infrared telescopes. This paper reports the results of the trial production of three key optical elements for a small format (number of slice;...

Slow-Scan Observations with the Infrared Camera (IRC) aboard AKARI

Satoshi Takita Norio Ikeda Yoshimi Kitamura Daisuke Ishihara Hirokazu Kataza Akiko Kawamura Shinki Oyabu Munetaka Ueno Issei Yamamura

PUBLICATIONS OF THE ASTRONOMICAL SOCIETY OF JAPAN 64(6) 2012年12月

We present the characterization and calibration of the slow-scan observation mode of the Infrared Camera (IRC) aboard AKARI. The IRC Slow-scan observations were operated at the S9W (9 mu m) and Ll8W (18 mu m) bands. We developed a toolkit for data...

THE ABSENCE OF COLD DUST AROUND WARM DEBRIS DISK STAR HD 15407A

ASTROPHYSICAL JOURNAL LETTERS 759(1) 2012年11月

We report Herschel and AKARI photometric observations at far-infrared (FIR) wavelengths of the debris disk around the F3V star HD 15407A, in which the presence of an extremely large amount of warm dust (similar to 500-600 K) has been suggested by ...

MID-INFRARED IMAGING OF THE TRANSITIONAL DISK OF HD 169142: MEASURING THE SIZE OF THE GAP

The disk around the Herbig Ae star HD 169142 was imaged and resolved at 18.8 and 24.5 mu m using Subaru/COMICS. We interpret the observations using a two-dimensional radiative transfermodel and find evidence for the presence of a large gap. The mi...
