On the mass and luminosity functions of tidal disruption flares: rate suppression due to black hole event horizons

S van Velzen - The Astrophysical Journal, 2018 - iopscience.iop.org
The tidal disruption of a star by a massive black hole is expected to yield a luminous flare of
thermal emission. About two dozen of these stellar tidal disruption flares (TDFs) may have …
