Radiation Dynamics, Envelope Ejection, and Supernova Light Curves
Abstract
Supernova light curves are interpreted within a shock wave model for envelope ejection. The hydrodynamical and radiative transport physics and the calculational method are summarized. The light curves are examined for numerical models (presented in tables) for two classes of presupernova configuration. The effects of outer-envelope and highly extended (R0 1015 cm) presupernova structures on the luminosity peak epoch are emphasized. Implications for explosion energetics, presupernova mass loss, Rayleigh-Taylor instabilities in the ejecta, and exposure of underlying regions are discussed.
