Supernovae from Single Stars and Interacting Binaries

There has been dramatic recent progress in our understanding of core-collapse supernovae. This, for the first time, has allowed us to connect supernova progenitors with their supernova explosions (if successful) and their remnants. Some of these predictions are currently testable with O4 LIGO observations. Here were report the implications of these developments for supernovae from single stars and stars having experienced a binary interaction. For the latter, we have systematically explored stars that have been stripped by binary interactions, have accreted from a companion or merged with a companion completely. We present the observational properties of their progenitors at the time of the explosion and the predictions for the resulting supernovae. This has important implications for supernovae of various types, ranging from SNe IIP to supernovae with blue supergiant progenitors (similar to SN 1987A), supernovae from yellow supergiants and supernovae exploding in an LBV phase. It also predicts the properties of the progenitors of stars where the supernova fails, leading to the formation of black holes.
