Recalculation of the spectrum of radiation emitted during gravitational collapse
Jun, 2004Citations per year
Abstract: (arXiv)
We recalculate the spectrum of radiation emitted from a collapsing star. We consider the simple model of a spherical star consisting of pressure-free dust and we derive the thermal spectrum via a systematic asymptotic expansion of the complete Bogolubov amplitude. Inconsistencies in previous derivations are pointed out.- 04.70.Dy
