Abstract

This paper (see also Moskvitin et al. 2010, Astroph. Bull., 65, 230, arXiv:1008.0773) describes the aims, objectives and first results of the observational program for the study of core-collapse supernovae (CCSNe). This work is done within the framework of an international cooperation program on the CCSNe monitoring at the 6-m BTA telescope of the SAO RAS and other telescopes. We study both the early (SN type determination, redshift estimation, and a search for manifestations of a wind envelope) and the nebular phases (the effects of explosion asymmetry) of CCSNe. The SNe associated with cosmic gamma-ray bursts (GRBs) are of particular interest. An interpretation of our observational data along with the data obtained on other telescopes is used to test the existing theoretical models of both the SN explosion and the surrounding circumstellar medium.
