Blast from the past: constraining progenitor models of SN 1972E
Blast from the past: constraining progenitor models of SN 1972E
We present a novel technique to study Type Ia supernovae by constraining surviving companions of historical extragalactic SN by combining archival photographic plates and Hubble Space Telescope imaging. We demonstrate this technique for Supernova 1972E, the nearest known SN Ia in over 125 years. Some models of Type Ia supernovae …
