Impact of the Galactic Disk and Large Magellanic Cloud on the Trajectories of Hypervelocity Stars Ejected from the Galactic Center
Scott J Kenyon, Benjamin C. Bromley, Warren R. Brown +1
We consider how the gravity of the Galactic disk and the Large Magellanic Cloud (LMC) modifies the radial motions of hypervelocity stars (HVSs) ejected from the Galactic Center. Fo…
Proper Motions and Trajectories for 16 Extreme Runaway and Hypervelocity Stars
Warren R. Brown, Jay Anderson, Oleg Y. Gnedin +3
We measure proper motions with the Hubble Space Telescope for 16 extreme radial velocity stars, mostly unbound B stars in the Milky Way halo. Twelve of these stars have proper moti…
Predicted Space Motions for Hypervelocity and Runaway Stars: Proper Motions and Radial Velocities for the GAIA Era
Scott J. Kenyon, Benjamin C. Bromley, Warren R. Brown +1
We predict the distinctive three dimensional space motions of hypervelocity stars (HVSs) and runaway stars moving in a realistic Galactic potential. For nearby stars with distances…
MMT Hypervelocity Star Survey III: A Complete Survey of Faint B-type Stars in the Northern Milky Way Halo
Warren R. Brown, Margaret J. Geller, Scott J. Kenyon
We describe our completed spectroscopic survey for unbound hypervelocity stars (HVSs) ejected from the Milky Way. Three new discoveries bring the total number of unbound HVSs to 21…
The Origin of HVS17, an Unbound Main Sequence B Star at 50 kpc
Warren R. Brown, Judith G. Cohen, Margaret J. Geller +1
We analyze Keck ESI spectroscopy of HVS17, a B-type star traveling with a Galactic rest frame radial velocity of +445 km/s in the outer halo of the Milky Way. HVS17 has the project…
