On a possible gamma-ray burst-supernova time sequence

The data from the Chandra satellite on the iron emission lines in the after glow of GRB 991216 are used to give further support to the theory that link s the origin of the energy of gamma-ray bursts (GRBs) to the extractable en ergy of electromagnetic black holes (EMBHs), leading to an interpretation o f the GRB-supernova correlation. Following the relative spacetime transform ation paradigm and the interpretation of the burst structure paradigm, we i ntroduce a paradigm for the correlation between GRBs and supernovae. The fo llowing sequence of events is shown as kinematically possible and consisten t with the available data: (1) the GRB-progenitor star P-1 first collapses into an EMBH; (2) the proper GRB and the peak of the afterglow (the extende d afterglow peak emission) propagate in interstellar space until the impact on a supernova-progenitor star P-2 at a distance less than or equal to2.69 x 10(17) cm, and they induce the supernova explosion; and (3) the accelera ted baryonic matter pulse, originating the afterglow, reaches the supernova remnants 18.5 hr after the supernova explosion and gives rise to the iron emission lines. Some considerations of the dynamical implementation of the paradigm are presented. The concept of an induced supernova explosion, intr oduced here specifically for the GRB-supernova correlation, may have a more general application in relativistic astrophysics.
