Ryo Kandori,Yasushi Nakajima,Motohide Tamura,Ken'ichi Tatematsu,Yuri Aikawa,Takahiro Naoi,Takahiro Naoi,Koji Sugitani,Hidehiko Nakaya,Takahiro Nagayama,Tetsuya Nagata,Mikio Kurita,Daisuke Kato,Chie Nagashima,Shuji Sato +14 more
TL;DR: In this article, the authors derived the visual extinction distribution toward 10 Bok globules through measurements of both the color excess (EH-K) and the stellar density at J, H, and Ks (star count).

Variable stars in the Magellanic Clouds: results from OGLE and SIRIUS
Yoshifusa Ita,Toshihiko Tanabe,Noriyuki Matsunaga,Yasushi Nakajima,Chie Nagashima,Takahiro Nagayama,Daisuke Kato,Mikio Kurita,Tetsuya Nagata,Shuji Sato,Motohide Tamura,Hidehiko Nakaya,Yoshikazu Nakada +12 more
TL;DR: In this paper, a cross-identification between OGLE-II data and single-epoch Simultaneous three-colour Infrared Imager for Unbiased Surveys (SIRIUS) near-infrared (NIR) JHK survey data in the Large and Small Magellanic Clouds (LMC and SMC, respectively) was performed.

Journal ArticleDOI
Clustering of Pre-Main-Sequence Stars in the Orion, Ophiuchus, Chamaeleon, Vela, and Lupus Star-forming Regions
TL;DR: In this paper, the average surface density of pre-main-sequence stars in the Orion, Ophiuchus, Chamaeleon, Vela, and Lupus star-forming regions was calculated as a function of angular distance from each star.
Journal ArticleDOI
Near-Infrared Imaging Polarimetry of the Star-Forming Region NGC 2024
Ryo Kandori,Motohide Tamura,Nobuhiko Kusakabe,Yasushi Nakajima,Takahiro Nagayama,Chie Nagashima,Jun Hashimoto,Akika Ishihara,Tetsuya Nagata,J. H. Hough +9 more
TL;DR: In this article, a prominent and extended polarized nebula over NGC 2024 was found and constrained the location of the illuminating source of the nebula through the analysis of polarization vectors, where a massive star, IRS 2b, is located in the center of the symmetric vector pattern.
