Spin the black circle II: tidal heating and torquing of a rotating black hole by a test mass on generic orbits
Rossella Gamba, Danilo Chiaramello, Estuti Shukla +1
Horizon fluxes of energy and angular momentum are a key strong-field effect in the dynamics of black holes, encoding direct information about their nature. In this work, we present…
