Scientific paper
The supernova explosion of type II is a collapse of a massive (M* > 8M Sun ) star which becomes hydrodynamically unstable by the exhaustion of its nuclear fuel. According the studies has been developed today, there are some unresolved problems in this phenomena. One of them is that, what kind of nuclear equation of state characterises well the matter of the collapsing core. In SN II numerical simulations we try to solve the classical hydrodynamical differential equations of a perfect fluid among very cruel conditions (shock waves appears etc.). In this paper I would like to show a development of a very simple model of the collapse of a massive star in one and two dimensional spherical geometry established to examine the raise of the core bounce and the growth of perturbation in two dimension before the bounce occurs.
