Observational Constraints on the Origin of the Galactic center S-stars

The formation mechanism of the young S-stars located within an arcsecond of the supermassive black hole remains a mystery. Proposed formation scenarios for these S-stars include the tidal disruption of a binary system and migration from the clockwise disk of young stars.

The Oldest Extremely Metal-poor Stars
