Which Star Becomes Which Supernova?
Supernova research is presently in the limelight, and new types of supernova are being discovered, leading to a zoo of types, each with their own particular behavior. As discussed by Shaviv, the theory of supernovas (SN) has not yet produced any ‘successful explosion’, so we describe here only what the extensive work by various modelers seems to suggest. Masses given relate to the moment just prior to the SN explosion. The initial star on the main sequence would certainly have been more massive and would have lost significant amounts of matter during its evolution toward the critical moment at which it exploded.
