| Abstract: | Hydrodynamical evolution of a collapsing stellar core is followed to test the influence of general relativity and of softening effects in the equation of state. The general relativistic treatment of the collapse does not show any spectacular deviation from the Newtonian treatment. In particular there is no indication within the standard scenario for potential barrier penetration and continued collapse to a black hole. In the case of strong electron capture during the collapse the nuclear matter equation of state is of importance. A softening according to a phase transition below the bounce density is found to reduce the shock strength, but the shock is strong enough to cause the usual blowing-off. |
