Mid-infrared spectroscopy of zodiacal emission with AKARI/IRC
Aoi Takahashi, Takafumi Ootsubo, Hideo Matsuhara +3
Interplanetary dust (IPD) is thought to be recently supplied from asteroids and comets. Grain properties of the IPD can give us the information about the environment in the proto-s…
Subaru/HiCIAO imaging of LkH 330 - multi-band detection of the gap and spiral-like structures
Taichi Uyama, Jun Hashimoto, Takayuki Muto +56
We present - and -bands observations of the LkH 330 disk with a multi-band detection of the large gap and spiral-like structures. The morphology of the outer disk…
High-resolution 25 μm imaging of the disks around Herbig Ae/Be stars
M. Honda, K. Maaskant, Y. K. Okamoto +12
We imaged circumstellar disks around 22 Herbig Ae/Be stars at 25 μm using Subaru/COMICS and Gemini/T-ReCS. Our sample consists of equal numbers of objects belonging to the two cate…
Low-Resolution Spectrum of the Zodiacal Light with AKARI InfraRed Camera
Kohji Tsumura, Toshio Matsumoto, Shuji Matsuura +3
We present the near- and mid-infrared zodiacal light spectrum obtained with the AKARI Infra-Red Camera (IRC). A catalog of 278 spectra of the diffuse sky covering a wide range of G…
Mid-IR imaging of the transitional disk of HD169142: Measuring the size of the gap
M. Honda, Koen Maaskant, Y. K. Okamoto +14
The disk around the Herbig Ae star HD\,169142 was imaged and resolved at 18.8 and 24.5\,m using Subaru/COMICS. We interpret the observations using a 2D radiative transfer model…
Pre-transitional disk nature of the AB Aur disk
M. Honda, A. K. Inoue, Y. K. Okamoto +12
The disk around AB Aur was imaged and resolved at 24.6\,m using the Cooled Mid-Infrared Camera and Spectrometer on the 8.2m Subaru Telescope. The gaussian full-width at half-max…
