Abstract:
Eccentric nuclear disks, like the one in the Andromeda galaxy, are made up of stars on apsidally-aligned eccentric orbits. In this talk I will show how secular gravitational torques between the orbits not only maintains the stability of the nucleus but dramatically enhances the rates of tidal disruption events. As eccentric nuclear disks can form during gas-rich major mergers, this can explain the preference for tidal disruption events in recent- and post-merger galaxies.
