The core collapse supernovae, gamma-ray bursts and SN 1987A Vladimir V. Sokolov, Alberto J. Castro-Tirado, Tatyana N. Sokolova

Abstract

      If all long gamma-ray bursts (GRBs) are related to supernovae core-collapse supernovae (SNe) explosions indeed, then a long GRB is the collapse of a massive star core or the beginning of an axially symmetric explosion of SN, and the long GRBs must always be accompanied by an SN explosion (of Ib/c type or other types of core-collapse SNe). Then the total energy release of a burst source in gamma rays is in any case not higher that the total electromagnetic energy radiated by the SN (< or ∼ 10⁴⁹ erg). Within the context of the model of asymmetric explosion of such SNe it is discussed when the relation GRB-SN is observed and when it is not observed. The accumulated statistics of GRB + SN coincidences will confirm the GRB compact model more and more. And we tell about the study of GRBs in SAO RAS, about optical identification of the first ten of GRBs.
