We introduce the Dichroic-Mirror Camera (DMC), an instrument developed at the University of Tokyo which is capable of performing simultaneous imaging in fifteen bands. The main feature of the DMC is...
Hyper Suprime-Cam : back-end electronics for CCD readout (2008)
Uchida, Tomohisa, Miyatake, Hironao, Nakaya, Hidehiko, Aihara, Hiroaki, Miyazaki, Satoshi
The development status of a prototype readout module for Hyper Suprime-Cam, a next-generation prime-focus camera for the 8.2 m Subaru Telescope, is presented. The camera has a field of view 1.5° in...
Sequential star formation in a cometary globule (BRC37) of IC1396 (2008)
Ikeda, Hisashi, Sugitani, Koji, Watanabe, Makoto, Fukuda, Naoya, Tamura, Motohide, Nakajima, Yasushi, ...
We have carried out near-IR/optical observations to examine star formation toward a bright-rimmed cometary globule (BRC37) facing the exciting star(s) of an HII region (IC1396) containing an IRAS...
The period-luminosity relation for type II Cepheids in globular clusters (2006)
Matsunaga, Noriyuki, Fukushi, Hinako, Nakada, Yoshikazu, Tanabe, Toshihiko, Feast, Michael W., Menzies, John W., ...
We report the result of our near-infrared observations (JHKs) for type II Cepheids (including possible RV Tau stars) in galactic globular clusters. We detected variations of 46 variables in 26...
Near Infrared Imaging Survey of Bok Globules: Density Structure (2005)
Kandori, Ryo, Nakajima, Yasushi, Tamura, Motohide, Tatematsu, Ken'ichi, Aikawa, Yuri, Naoi, Takahiro, ...
On the basis of near-infrared imaging observations, we derived visual extinction (Av) distribution toward ten Bok globules through measurements of both the color excess (E_{H-K}) and the stellar...
A Distinct Structure Inside the Galactic Bar (2005)
Nishiyama, Shogo, Nagata, Tetsuya, Baba, Daisuke, Haba, Yasuaki, Kadowaki, Ryota, Kato, Daisuke, ...
We present the result of a near-infrared (J H Ks) survey along the Galactic plane, -10.5deg < l < +10.5deg and b=+1.0deg, with the IRSF 1.4m telescope and the SIRIUS camera. Ks vs. H-Ks...
Current performance and on-going improvements of the 8.2 m Subaru Telescope (2004)
Iye, Masanori, Karoji, Hiroshi, Ando, Hiroyasu, Kaifu, Norio, Kodaira, Keiichi, Aoki, Kentaro, ...
An overview of the current status of the 8.2m Subaru Telescope constructed and operated at Mauna Kea, Hawaii, by the National Astronomical Observatory of Japan is presented. The basic design concept...
Variable stars in the Magellanic Clouds: II. The data and infrared properties (2003)
Ita, Yoshifusa, Tanabe, Toshihiko, Matsunaga, Noriyuki, Nakajima, Yasushi, Nagashima, Chie, Nagayama, Takahiro, ...
The data of 8,852 and 2,927 variable stars detected by OGLE survey in the Large and Small Magellanic Clouds are presented. They are cross-identified with the SIRIUS JHK survey data, and their...
The Infrared Counterpart of the X-Ray Nova XTE J1720-318 (2003)
Nagata, Tetsuya, Kato, Daisuke, Baba, Daisuke, Nishiyama, Shogo, Nagayama, Takahiro, Nagashima, Chie, ...
We report on the discovery of an infrared counterpart to the X-ray transient XTE J1720-318 on 2003 January 18, nine days after an X-ray outburst, and the infrared light curve during the first 130...
Variable Stars in the Magellanic Clouds: Results from OGLE and SIRIUS (2003)
Ita, Yoshifusa, Tanabe, Toshihiko, Matsunaga, Noriyuki, Nakajima, Yasushi, Nagashima, Chie, Nagayama, Takahiro, ...
We have performed a cross-identification between OGLE-II data and single-epoch SIRIUS JHK survey data in the LMC and SMC. After eliminating obvious spurious variables, we determined the pulsation...
Pulsation at the tip of the first giant branch? (2002)
