Supergiant GCIRS 22 in the Milky Way Nuclear Star Cluster: Revised alpha abundances
B. Thorsbro, S. Khalidy, R. M. Rich +7
Context: The chemical abundances of alpha-elements in Galactic Centre (GC) supergiants provide key insights into the chemical enrichment and star formation history of the Milky Way…
Discovery of WINERED-HVS1: A metal-rich hyper-velocity star candidate ejected from the Galactic center
Kohei Hattori, Daisuke Taniguchi, Takuji Tsujimoto +4
We report the discovery of a metal-rich red giant star, WINERED-HVS1, which is a candidate for a hyper-velocity star (HVS). Its past trajectory suggests that this star may have bee…
MAGIS (Measuring Abundances of red super Giants with Infrared Spectroscopy) project I. Establishment of an abundance analysis procedure for red supergiants and its evaluation with nearby stars
Daisuke Taniguchi, Noriyuki Matsunaga, Naoto Kobayashi +11
[Abbreviated] Context. Given their high luminosities (L>~10^4Lsun), red supergiants (RSGs) are good tracers of the chemical abundances of the young stellar population in the Milky…
