A model for ultrarelativistic spherically symmetric Pre-Hawking radiating gravitational collapse

Abstract

In this paper we present a simple but non-simplistic model of gravitational collapse with thermal emission of pre-Hawking radiation. We apply Einstein equations to a time-dependant spherically symmetric metric and an ultrarelativistic stress-energy tensor. In our model, particles either radially approach the center of the star as collapsing matter, or radially flee from it.

arXiv commentThis paper has been withdrawn by the author due to an inadequate treatment of the stress-momentum tensor and a not well-behaved radiation law. The right development may be found at arXiv: gr-qc\1406.4189
