ABSTRACT
Supernovae are generally produced in two different explosion mechanisms. The one via the thermonuclear explosion of a white dwarf which has been accreting matter from a companion is known as a Type Ia supernova. In the second instance, core-collapse of massive stars produce Type II, Type Ib and Type Ic supernovae. The core collapse forces protons and electrons together to produce neutrons and electron neutrinos. The neutrinos escape, as they interact so feebly with other matter, and take energy away from the core, which accelerates the collapse. The collapse is the result of the tug of war between the two weakest known forces of nature-gravity and weak interaction. The weak processes like the capture of electrons by nuclei and protons and beta decay plays vital role during silicon burning. The situation in supernova modeling is that self-consistent spherically-symmetric calculations do not yield successful explosions based on neutrino energy deposition from the hot collapsed central core into the adjacent layers.
