read the original abstract
The efficiency of thin disk accretion onto black holes depends on the inner boundary condition, specifically the torque applied to the disk at the last stable orbit. This is usually assumed to vanish. I estimate the torque on a magnetized disk using a steady magnetohydrodynamic inflow model originally developed by Takahashi et al., 1990. I find that the efficiency epsilon can depart significantly from the classical thin disk value. In some cases epsilon > 1, i.e. energy is extracted from the black hole.

Triple radio flares from tidal disruption events: jet-wind collisions and the discovery of a third radio flare from AT2020vwl
The TDE AT2020vwl showed a third radio flare at the time a jet-wind collision was predicted from its first two flares, the first predicted-and-confirmed third flare.

Orbital Motion in Spacetimes Influenced by the Presence of Scalar and Electromagnetic Fields
Strong scalar fields around naked singularities can create stable circular orbits, and charged scalar-field spacetimes can host both stable and unstable photon orbits.
