Mass Segregation in Eccentric Nuclear Disks: Enhanced Tidal Disruption
  Event Rates for High Mass Stars
  Eccentric nuclear disks (ENDs) are a type of star cluster in which the stars
lie on eccentric, apsidally-aligned orbits in a disk around a central
supermassive black hole (SMBH). These disks can produce a high rate of tidal
disruption events (TDEs) via secular gravitational torques. Previous studies of
ENDs have included stars with only one mass. Here, we present the first study
of an eccentric nuclear disk with two stellar species. We show that ENDs show
radial mass segregation consistent with previous results from other cluster
types. Additionally, ENDs show vertical mass segregation by which the heavy
stars sink to lower inclinations than light stars. These two effects cause
heavy stars to be more susceptible to tidal disruption, which can be seen in
the higher fraction of heavy stars that are disrupted compared to light stars.
