MODELING TYPE la SUPERNOVAE AND QUARK NOVAE

摘要

Compact astrophysical objects can change their structure and composition in combustion-like processes. In the case of white dwarfs, thermonuclear burning can even lead to an explosion as a Type la supernova. We give a brief account of the physical concepts of combustion and of methods to model this phenomenon in large-scale numerical simulations. As examples for application we discuss thermonuclear explosions of white dwarfs and to hypothetical "quark novae" transforming neutron stars into strange quark stars. supernovae
