[45.01] Photometry of Supernova Host Galaxies

K. Hole (Oberlin Coll.), R. McMillan, R. Ciardullo (Penn State U.)

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.
