[38.04] Type II Supernova Light Curves: Influence of the He Core Mass

T. R. Young, E. Baron, and D. Branch (University of Oklahoma)

A study of numerical Type II supernova light curves showing the effects of various helium core masses is carried out. The simulations use a 1-dimensional, flux-limited hydrodynamical code which accesses opacity tables and accounts for gamma ray deposition. Presupernova models used in this study have helium core masses of about 2, 3, 4, 6, and 8 $M_\odot$, taken from calculations by Nomoto and Woosley. The hydrogen envelope is modified by homologous transformations to vary its radius and mass. The influence of the helium core mass on the shape and absolute magnitude of the light curve is shown independent of other parameters that affect the light curve.
