Modeling black hole evaporative mass evolution via radiation from moving mirrors

We investigate the evaporation of an uncharged and nonrotating black hole in vacuum by taking into account the effects given by the shrinking of the horizon area. These include the backreaction on the metric and other smaller contributions arising from quantum fields in curved spacetime. Our approach is facilitated by the use of an analog accelerating moving mirror. We study the consequences of this modified evaporation on the black hole entropy. Insights are provided on the amount of information obtained from a black hole by considering nonequilibrium thermodynamics and the nonthermal part of Hawking radiation.
