Mass function of a young cluster in a low-metallicity environment. Sh 2-209
Chikako Yasui, Naoto Kobayashi, Masao Saito +2
We present deep near-infrared (NIR) imaging of Sh 2-209 (S209), a low-metallicity ( dex) HII region in the Galaxy. From the NIR images, combined with astrometr…
Survey of near-infrared diffuse interstellar bands in and bands. I. Newly identified bands
Satoshi Hamano, Naoto Kobayashi, Hideyo Kawakita +12
We searched for diffuse interstellar bands (DIBs) in the 0.911.33 m region by analyzing the near-infrared (NIR) high-resolution ( and 28,000) spectra of 31 redden…
Star Formation Activity Beyond the Outer Arm II: Distribution and Properties of Star Formation
Natsuko Izumi, Naoto Kobayashi, Chikako Yasui +3
The outer Galaxy beyond the Outer Arm represents a promising opportunity to study star formation in an environment vastly different from the solar neighborhood. In our previous stu…
A Very Metal-poor RR Lyrae Star with a Disk Orbit Found in the Solar Neighborhood
Noriyuki Matsunaga, Akinori Itane, Kohei Hattori +28
Metal-deficient stars are important tracers for understanding the early formation of the Galaxy. Recent large-scale surveys with both photometric and spectroscopic data have report…
