The Nature of Hypervelocity Stars and the Time Between Their Formation and Ejection
Warren R. Brown, Judith G. Cohen, Margaret J. Geller +1
We obtain Keck HIRES spectroscopy of HVS5, one of the fastest unbound stars in the Milky Way halo. We show that HVS5 is a 3.62 +- 0.11 Msun main sequence B star at a distance of 50…
Binary Disruption by Massive Black Holes: Hypervelocity Stars, S Stars, and Tidal Disruption Events
Benjamin C. Bromley, Scott J. Kenyon, Margaret J. Geller +1
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…
MMT Hypervelocity Star Survey. II. Five New Unbound Stars
Warren R. Brown, Margaret J. Geller, Scott J. Kenyon
We present the discovery of five new unbound hypervelocity stars (HVSs) in the outer Milky Way halo. Using a conservative estimate of Galactic escape velocity, our targeted spectro…
