We present our analysis of a sample of type II supernova light curves measured by the Caltech Core Collapse Project (CCCP). CCCP is a large observational program which made use of the robotic 60" and the Hale 200" telescopes to obtain optical photometry, spectroscopy and IR photometry of 50 nearby core-collapse supernovae. It provides a complete sample of core-collapse events, with well-defined selection criteria, and uniform, high-quality optical/IR observations.
Our goal is to characterize the little-studied properties of core-collapse supernovae as a population. We attempt to describe the light curves of type II SNe of all subtypes using only a few empirically derived parameters, with the aspiration of explaining most of our light curves with a single tunable formula. Eventually, associating a physical meaning to each of the parameters may help to better understand the mechanisms underlying the diversity in type II SN light curves.
