A simple, similarity model is developed to model the explosive hydrodynamics and radiation of a supernova. The model has two periods of energy release, an earlier one representing the initial nuclear explosion or gravitational collapse, and a later one representing the longer-term radioactive decay energy. Because the model conserves mass, momentum and energy, the overall dynamics and the scaling connections between key variables is expected to be fairly accurate. The model is used to calculate luminosity versus time curves for a number of typical type I supernovae and compared with recent data from the Supernova Cosmology Project.

Key words: hydrodynamics -- methods: analytical -- stars: supernovae: general
