Synthetic Spectra for Supernovae II
Abstract
The results of an attempt to study the spectra of supernova photospheres using detailed photospheric models are reported. The photosphere is calculated assuming a spherical configuration, a density following a power law with exponent 10, the existence of LTE and radiative equilibrium, and expansion velocity increasing proportionally to the radius. The calculated spectra and effective temperature agree well with the observed spectrum of SN 1980 K. Interesting correspondences are found between the UV fluxes of SN 1987 A and the energy distribution of a blanketed model with T(eff) = 8000 K and v(exp) = 15,000 km/s.
