Bromley, Benjamin C. | Binary disruption by massive black holes: hypervelocity stars, S stars, and tidal disruption events | We examine whether disrupted binary stars can fuel black hole growth. In this mechanism, tidal disruption produces a single hypervelocity star (HVS) ejected at high velocity and a former companion star bound to the black hole. After a cluster of bound stars forms, orbital diffusion allows the black ... | | 2012-01-01 |
