Optical Properties of Interstellar Dust around the Orion A Molecular Cloud
Hayato Uehara, Kazuhito Dobashi, Shingo Nishiura +2
We have studied optical properties of interstellar dust around the Orion A molecular cloud to investigate the size distribution and the composition of dust grains. Orion A is one o…
OCTAD-S: Digital Fast Fourier Transform Spectrometers by FPGA
Kazumasa Iwai, Yûki Kubo, Hiromitsu Ishibashi +5
We have developed a digital fast Fourier transform (FFT) spectrometer made of an analog-to-digital converter (ADC) and a field-programmable gate array (FPGA). The base instrument h…
Maps of Massive Clumps in the Early Stage of Cluster Formation: Two Modes of Cluster Formation, Coeval or Non-Coeval?
Aya E. Higuchi, Yasutaka Kurono, Takahiro Naoi +3
We present maps of 7 young massive molecular clumps within 5 target regions in the C18O (J=1-0) line emission, using the Nobeyama 45m telescope. These clumps, which are not associa…
Atacama Compact Array Antennas
Masao Saito, Junji Inatani, Kouichiro Nakanishi +8
We report major performance test results of the Atacama Compact Array (ACA) 7-m and 12-m antennas of ALMA (Atacama Large Millimeter/submillimeter Array). The four major performance…
Direct Imaging of Bridged Twin Protoplanetary Disks in a Young Multiple Star
Satoshi Mayama, Motohide Tamura, Tomoyuki Hanawa +10
Studies of the structure and evolution of protoplanetary disks are important for understanding star and planet formation. Here, we present the direct image of an interacting binary…
The Infrared Astronomical Mission AKARI
H. Murakami, H. Baba, P. Barthel +90
AKARI, the first Japanese satellite dedicated to infrared astronomy, was launched on 2006 February 21, and started observations in May of the same year. AKARI has a 68.5 cm cooled…
