Low-metallicity Young Clusters in the Outer Galaxy. II. Sh 2-208
Chikako Yasui, Naoto Kobayashi, Masao Saito +1
We obtained deep near-infrared images of Sh 2-208, one of the lowest-metallicity HII regions in the Galaxy, [O/H] = -0.8 dex. We detected a young cluster in the center of the HII r…
Near infrared diffuse interstellar bands toward the Cygnus OB2 association
Satoshi Hamano, Naoto Kobayashi, Sohei Kondo +16
We obtained the near-infrared (NIR) high-resolution () spectra of the seven brightest early-type stars in the Cygnus OB2 association for investigating the en…
Herbig Ae/Be candidate stars in the innermost Galactic disk: Quartet cluster
Chikako Yasui, Naoto Kobayashi, Satoshi Hamano +4
In order to investigate the Galactic-scale environmental effects on the evolution of protoplanetary disks, we explored the near-infrared (NIR) disk fraction of the Quartet cluster,…
