Type Ia Supernovae Progenitors

Friday, March 13, 2020
2:00 PM - 3:00 PM
Location: Cahill 370
Robert Fisher, Associate Professor, Physics Department, UMass, Dartmouth

Type Ia supernovae (SNe Ia), resulting from the detonation of white dwarfs (WDs), play an important role as standardizable candles for cosmology. Yet, the nature of their stellar progenitors remains a largely unsolved problem. In this talk, I will present recent multidimensional simulations of both the single and double-degenerate channels of SNe Ia. I will also discuss the use of late-time (> 1000 d past maximum) light curves to constrain both the progenitor WD masses as well as the uncertain ignition and detonation mechanisms of SNe Ia. I will conclude with implications for the SN Ia stellar progenitor problem.
