Based on spectral features' presence/absence, they are sub-classified into different categories. The progenitors of the supernovae sub-types also differ. Direct imaging has detected progenitors of about two dozen type IIP supernovae ranging between 8-20 M_sun. Direct imaging has not resulted in progenitor detection for other subtypes except in a few cases. Indirect methods can be used to determine the nature of the progenitor, such as light curve modelling, nebular phase spectrum modelling, and the use of line ratios and nucleosynthesis yields. In this talk, I will review the different methods and discuss the results obtained for the supernovae sub-types. I will briefly discuss the continuity between the progenitors of various core-collapse supernova sub-types. |
