Session 45 - Supernovae.
Display session, Tuesday, January 14
As part of an ongoing study of the ages of Type Ia and Type II supernova progenitors, we present V and I broadband photometry of the regions underlying more than 50 extragalactic historical supernovae. We find some indication that regions hosting Type Ia supernovae show a broader variation in color than those of Type II supernovae. This is consistent with earlier results from this project and others showing that Type Ia supernovae arise from intermediate-age stars that have had sufficient time to drift away from their formation regions.
