Research Abstract

Electron capture supernovae (ECSNe) are considered to be the lightest supernovae among the core-collapse SNe. In general stellar number increases for less massive stars. Therefore ECSNe should be important for the study of SN light curves and the origin of elements. However they have not been considered much in the study of these fields. One of the main reasons for this situation is that their progenitor models have rarely been calculated previously. This is because the physical processes during the stellar evolution is quite different from more massive Fe-core forming stars, and are very complicated.
In this study we successfully calculated progenitor models for ECSNe with up-dated input physics after about 30 years since the previous calculation. With applying these progenitor models for explosion simulations, we expect that our understanding about ECSNe will improve in near future.
