We present calculations of supernova (SN) light curves that assume the existence of a central pulsar. We have shown in Paper I that absorption of the pulsar waves can occur only after some cooling has taken place, and that the pulsar acts as a thermostat, keeping central temperature fixed around 1.3 x 10/sup 4/ K. The main absorption process is particle acceleration by the strong waves. Several difficulties inherent in most existing models are solved in this way, especially the rapid rise of luminosity before maximum, and the observed high values of expansion velocities. A good fit of the typical SN Type II light curves has been obtained. Furthermore, the continuous spectrum and the observed temperatures of about 1.0 x 10/sup 4/ K near maximum can be explained easily in this model.
