Supernova Progenitors
As of 2010 over thirty core-collapse SN progenitors have been identified. What do they look like? Generally they are all massive stars (a plus for SN theory); furthermore Type II-P supernova typically have progenitors that are red supergiants at the low-mass end. The question is whether all massive stars result in SN. Kochanek has suggested we look for massive stars vanishing from nearby galaxies. This might be quite feasible and interesting.
