Abstract

We find two empirical scaling laws in the solar system, which is evidence that the most probable origin of the p-nuclei is photodisintegration reactions in supernova explosions (p-process). We also find a novel concept of "the universality of the p-process". We discuss the mechanism of this universality in typical core-collapse supernova explosion models.
