Shock breakout in SN 1987A

TLDR: In this article, a two-temperature radiation hydrodynamics code was used to model the UV burst from SN 1987A using a two temperature radiation hydrogrographic code.

Abstract: Detailed models for the UV burst from SN 1987A are calculated using a two-temperature radiation hydrodynamics code The sequence of events which occur during shock breakout is described, including the formation of a radiative precursor, the disappearance of the shock, and the growth of a thin, dense shell above the photosphere which gives rise to a new viscous, isothermal shock Continuum spectra are calculated under the assumption that the emergent radiation is a dilute blackbody with a color temperature equal to the radiation temperature at the thermalization depth This color temperature is 2-3 times higher than the effective temperature Light-travel-time corrections have been included in the light curves and the spectra Quantities most relevant to accurate modeling of the fluorescing ring around SN 1987A are highlighted
