Ejecta masses in Type Ia Supernovae -- Implications for the Progenitor and the Explosion Scenario

Zsófia Bora, Réka Könyves-Tóth, József Vinkó +35

The progenitor system(s) as well as the explosion mechanism(s) of thermonuclear (Type Ia) supernovae are long-standing issues in astrophysics. Here we present ejecta masses and oth…
