The Diversity of Light Curves of Supernovae Associated with Gamma-Ray Bursts

More than 10000 gamma-ray bursts (GRBs) have been detected since discovery. Long-term observations of about 850 GRB afterglow in optic since 1998 have shown that a core-collapse supernova (SN) accompanies about 50 nearby GRB sources. We have collected about two dozen SNe’ multicolor light curves associated with GRBs. The sample is based on published data, obtained during observations of GRB-SN cases by ground-based observatories all around the world including our own observations. A description of the procedure for the extraction of the SN’s light curve, its analysis, and phenomenological classification of SNs are presented. We also discuss the current status and problems of investigations of SN associated with GRB.
