Scientific paper

The Hugionot equations for shock waves propagating in the neutrino-opaque interior of collapsing stars are formulated. The equations are solved numerically for a fairly wide range of shock wave velocities and values of physical parameters of the matter in front of the shock wave. It is shown that the presence of the neutrino radiation results in a considerable deneutronization (down to theta = 10-30) of the shocked matter, although the contribution of the leptonic component to the main physical quantitites is quite small.
