ABSTRACT

Among the most spectacular events in astrophysics are phenomena from the late phase of stellar evolution, namely the explosion of massive stars. Such events are called supernovae and some of them are extremly luminous neutrino sources. Neutrinos are emitted in a period of about 10 s and roughly equal in number those emitted by the Sun during its life. The physics of supernova explosions is rather complex; however, additional information can be found in [Sha83, Arn84, Woo86a, Arn89, Pet90, Whe90, Woo92, Woo94, Bur95, Mu¨l95c, Raf96, Bur97, Raf99, Ful01, Ham03, Fry04, Mez05, Woo05, Jan07].
