Discovery of WINERED-HVS1: A Metal-rich Hypervelocity Star Candidate Ejected from the Galactic Center
We report the discovery of a metal-rich red-giant star, WINERED-HVS1, which is a candidate for a hypervelocity star (HVS). Its past trajectory suggests that this star may have been ejected by the Galactic supermassive black hole (SMBH; Sgr A*), with a modest ejection velocity of at least 500 km s ^−...
