Scientific paper

A study of the recently discovered Type IIb supernova 1993J in the galaxy M81 indicates that the mass of the ejected envelope was approximately 2.4 solar mass including a hydrogen mass of approximately 0.75 solar mass, the explosion energy was approximately 1.6 x 1051 ergs, and the mass of radioactive Ni-56 nuclides was approximately 0.06 solar mass. In our model, the outburst of supernova 1993J is interpreted as the explosion of a approximately 4 solar mass red supergiant undergoing core collapse and leaving a neutron star in a binary system. The progenitor is supposed to have a helium core mass of approximately 3 solar mass corresponding to a approximately 12 solar mass main-sequence star. Supernova 1993J reveals physical similarities with Type II-P supernova 1987A and adds evidence to the scenario that Type Ib supernovae originate from moderately massive stars on the main sequence which have lost their hydrogen envelopes in interacting binary systems.
