Kerzendorf, Wolfgang; Schmidt, Brian; Laird, J.B.; Podsiadlowski, Ph.; Bessell, Michael

Description

Type Ia supernovae play a significant role in the evolution of the universe and have a wide range of applications. It is widely believed that these events are the thermonuclear explosions of carbon-oxygen white dwarfs close to the Chandrasekhar mass (1.38 M⊙). However, CO white dwarfs are born with masses much below the Chandrasekhar limit and thus require mass accretion to become Type Ia supernovae. There are two main scenarios for accretion: first, the merger of two white dwarfs and, second,...[Show more]
