HYPERVELOCITY STARS AND MASSIVE BLACK HOLES
Dr. Warren R. Brown
Havard
Host: Scott Hughes
Abstract:
Hypervelocity stars ejected from the Galaxy at ~1000 km/s are a
natural consequence of the massive black hole in the Galactic center. We
discovered the first hypervelocity star in 2005, and we designed a survey
that has found 12 more of these unbound stars. Hypervelocity stars are
interesting because their observed spatial and velocity distributions are
linked to the black hole ejection mechanism.
