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…
Observations of the Optical Transient in NGC 300 with AKARI/IRC: Possibilities of Asymmetric Dust Formation
R. Ohsawa, I. Sakon, T. Onaka +10
We present the results of near-infrared (NIR) multi-epoch observations of the optical transient in the nearby galaxy NGC300 (NGC300-OT) at 398 and 582 days after the discovery with…
PAH emission from the dust lane of an elliptical galaxy with the Spitzer IRS
Hidehiro Kaneda, Takashi Onaka, Itsuki Sakon +5
Spitzer and AKARI observations have found that polycyclic aromatic hydrocarbons (PAHs) are present in nearby elliptical galaxies, but their spatial distributions are still unknown.…
Spectroscopic observations of ices around embedded young stellar objects in the Large Magellanic Cloud with AKARI
Takashi Shimonishi, Takashi Onaka, Daisuke Kato +4
The aim of this study is to understand the chemical conditions of ices around embedded young stellar objects (YSOs) in the metal-poor Large Magellanic Cloud (LMC). We performed nea…
The AKARI/IRC Mid-Infrared All-Sky Survey
Daisuke Ishihara, Takashi Onaka, Hirokazu Kataza +30
Context : AKARI is the first Japanese astronomical satellite dedicated to infrar ed astronomy. One of the main purposes of AKARI is the all-sky survey performed with six infrared b…
Detection of unidentified infrared bands in a Halpha filament in the dwarf galaxy NGC1569 with AKARI
Takashi Onaka, Hiroko Matsumoto, Itsuki Sakon +1
We performed observations of NGC1569 for 6 infrared bands (3.2, 4.1, 7, 11, 15, and 24 micron) with the Infrared Camera (IRC) onboard AKARI. Near- to mid-infrared (2--13 micron) sp…
