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…
The ALMA Survey of 70 Dark High-mass Clumps in Early Stages (ASHES). VII: Chemistry of Embedded Dense Cores
Shanghuo Li, Patricio Sanhueza, Xing Lu +15
We present a study of chemistry toward 294 dense cores in 12 molecular clumps using the data obtained from the ALMA Survey of 70 dark High-mass clumps in Early Stages (ASH…
The ALMA Survey of 70 μm Dark High-mass Clumps in Early Stages (ASHES). VI. The core-scale CO-depletion
Giovanni Sabatini, Stefano Bovino, Patricio Sanhueza +11
Studying the physical and chemical properties of cold and dense molecular clouds is crucial for the understanding of how stars form. Under the typical conditions of infrared dark c…
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…
