Near-Infrared Extinction in The Coalsack Globule 2
Takahiro Naoi, Motohide Tamura, Tetsuya Nagata +8
We have conducted J, H, and Ks imaging observations for the Coalsack Globule 2 with the SIRIUS infrared camera on the IRSF 1.4 m telescope at SAAO, and determined the color excess…
The period-luminosity relation for type II Cepheids in globular clusters
Noriyuki Matsunaga, Hinako Fukushi, Yoshikazu Nakada +11
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 var…
Interstellar Extinction Law in the J, H, and Ks Bands toward the Galactic Center
Shogo Nishiyama, Tetsuya Nagata, Nobuhiko Kusakabe +8
We have determined the ratios of total to selective extinction in the near-infrared bands (J, H, Ks) toward the Galactic center from the observations of the region |l| < 2.0deg and…
Near Infrared Imaging Survey of Bok Globules: Density Structure
Ryo Kandori, Yasushi Nakajima, Motohide Tamura +11
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}) a…
A Distinct Structure Inside the Galactic Bar
Shogo Nishiyama, Tetsuya Nagata, Daisuke Baba +16
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.…
A Young Brown Dwarf Companion to DH Tauri
Yoichi Itoh, Masahiko Hayashi, Motohide Tamura +20
We present the detection of a young brown dwarf companion DH Tau B associated with the classical T Tauri star DH Tau. Near-infrared coronagraphic observations with CIAO on the Suba…
