On the Hawking effect

2001 Physical Review D, Particles and fields  
In terms of the Painlevé-Gullstrand-Lemaître coordinates a rather general scenario for the gravitational collapse of an object and the subsequent formation of a horizon is described by a manifestly C^∞-metric. For a 1+1 dimensional model of the collapse the leading contributions to the Bogoliubov coefficients are calculated explicitely and the Hawking temperature is recovered. But depending on the particular dynamics of the collapse the final state represents either evaporation or
