Time-dependent photoionization opacities in dense gamma-ray burst environments.

LAZZATI D., PERNA R. and GHISELLINI G.

Abstract (from CDS):

The recent detection of a transient absorption feature in the X-ray prompt emission of GRB 990705 showed the importance of such observations in the understanding of gamma-ray bursts and their progenitors. We investigate the time dependence of photoionization edges during the prompt emission of bursts in different environments. We show that their variability can be used to infer the density and geometry of the surrounding medium, giving important clues to unveil the nature of the burst progenitor.
