Black hole evaporation in conformal gravity
Abstract
We study the formation and the evaporation of a spherically symmetric black hole in conformal gravity. From the collapse of a spherically symmetric thin shell of radiation, we find a singularityfree nonrotating black hole. This black hole has the same Hawking temperature as a Schwarzschild black hole with the same mass, and it completely evaporates either in a finite or in an infinite time, depending on the ensemble. We consider the analysis both in the canonical and in the microcanonical statistical ensembles. Last, we discuss the corresponding Penrose diagram of this physical process.
