Abstract

Recent efforts to model the processes occurring in Type I and II supernovae, and the diagnostics used to model the events, are described. Both types of events release about the same amount of energy and produce heavy elements. Features which distinguish the two types of supernovae are summarized. Prominent stages in Type II events are reviewed, including the presupernova evolution of massive stars, core collapse and bounce. Processes occurring in a delayed explosion, e.g., failure of the shock and possible formation of a 'neutrinosphere', are discussed, along with nucleosynthesis during Type II explosions and features of peculiar Type II events.
