Description
In the last fifteen years, searches for the progenitors of core-collapse supernovae
in archival Hubble Space Telescope images have yielded progenitor candidates for ~10
nearby supernovae, and upper limits on the luminosity and mass for a further ~20. In
this talk, I discuss recent results from ongoing progenitor searches. In particular,
I focus on some of the open questions in progenitor research: whether all faint Type
IIP supernovae arise from low (~8M) progenitors, why we have not detected any high
mass red supergiant progenitors thus-far, and whether recent results demonstrate that
some stars can in fact explode as yellow supergiants.
