摘要：

Hypervelocity stars (HVSs) are stars escaping the Milky Way with speeds best explained by a slingshot from the Galaxy's central massive black hole. 3-body exchange interactions explain both the existence of HVS and the S-stars orbiting the black hole today. I discuss the growing observational and theoretical support for this picture, and highlight recent surprises, such as the anisotropic spatial distribution of HVSs. The distribution of HVSs is linked to the nature and environment of the Galactic Center.
