Revised rates of stellar disruption in galactic nuclei.


Abstract (from CDS):

We compute rates of tidal disruption of stars by supermassive black holes in galactic nuclei, using downwardly revised black hole masses from the MBH-σ relation. In galaxies with steep nuclear density profiles, which dominate the overall event rate, the disruption frequency varies inversely with assumed black hole mass. We compute a total rate for nondwarf galaxies of ∼10–5/yr/Mpc3, about a factor of 10 higher than in earlier studies. Disruption rates are predicted to be highest in nucleated dwarf galaxies, assuming that such galaxies contain black holes. Monitoring of a rich galaxy cluster for a few years could rule out the existence of intermediate-mass black holes in dwarf galaxies.
