O. Levin et A. Ori, INNER STRUCTURE OF AN EVAPORATING CHARGED BLACK-HOLE WITH INGOING CHARGED NULL FLUID, Physical review. D. Particles and fields, 54(4), 1996, pp. 2746-2752
We consider a charged black hole irradiated by a charged null fluid wi
th negative energy density. As a consequence of this influx, the black
hole's mass and charge shrink to zero after some finite retarded time
. This model was previously proposed as a toy model for an evaporating
charged black hole. Here we modify the model by changing one of the a
ssumptions made concerning the orbits of the null fluid. This leads to
a very different internal structure of the black hole.
