Cosmological gamma ray bursts (GRBs) possibly originate from accretion disks around stellar mass black holes. These could be formed after the merger of a double neutron star or black hole-neutron star binary. The dynamical evolution of the disk is important if one wishes to relate characteristic timescales with the observed duration and variability. We show here the results of such a set of calculations, relevant for short GRBs.

Resumen

Resumen

Los destellos de rayos gama cosmólogicos posiblemente provienen de discos de acreción alrededor de agujeros negros. Estos pueden ser produeto de una fusión binaria de objetos compactos. Resulta importante estudiar la evolución dinámica de estos discos si se quiere relacionar las escalas temporales características con la duración y variabilidad observada en destellos. Mostramos resultados de tales cálculos, relevantes para destellos cortos.
