A stream of hypervelocity stars from the Galactic Center.

GENEROZOV A.

Abstract (from CDS):

Recent observations have found a 1700 km s–1 star [S5-HVS1] that was ejected from the Galactic center approximately five million years ago. This star was likely produced by the tidal disruption of a binary. In particular, the Galactic center contains a few million year old stellar disk that could excite binaries to nearly radial orbits via a secular gravitational instability. Such binaries would be disrupted by the central supermassive black hole, and would also explain the observed cluster of B stars ∼0.01 pc from the Galactic center. In this paper we predict S5-HVS1 is part of a larger stream, and use observationally motivated N-body simulations to predict its spatial and velocity distributions.
