Cavallo-Rees classification revisited |
Abstract _ |
We revisit Cavallo and Rees classification given by the analysis of initial conditions in electron-positron-photon plasma which appears suddenly around compact astrophysical objects and gives origin to GRBs. We comment on each of the four scenarios proposed by Cavallo and Rees and discuss applicability of this diagram to describe evolution of GRB sources. We contrast this picture with the dynamical scenario which has been in the meantime identified in all GRB sources. |
