A Numerical Study of Gravitational Stellar Collapse

The dynamic gravitational collapse of stars of mass 1.25-10 M0. is calculated in terms of general relativity. Neutrino flow is calculated in considerable detail to evaluate whether the energy flow of neutrinos can produce mass ejection. Most stars evidently eject no mass by the process of neutrino transport during their collapse even though they radiate about 10 g of neutrinos. Only the low-mass star of 1.25 M0 ejects material mass, in this case 1.1 X 1032 g. In this latter case neutrino flow is not important.
