TL;DR: In this article, the authors reported the results of their near-infrared observations (JHK s ) for type II Cepheids (including possible RV Tau stars) in galactic globular clusters.
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.
