Abstract: |
The phenomenon of a supernova in most cases should start with a bright flash, caused by a shock wave emerging on the surface of the star after the phase of collapse or thermonuclear explosion in interiors. The detection of such outbursts associated with the supernova shock breakout can be used to obtain information about the explosion properties, presupernova parameters and is important for finding the star formation history. I present the results and current status of numerical simulation of light curves and spectra at the epoch of shock breakout in several models of supernovae taking into account multigroup radiative transfer and a number of relativistic effects. These simulations leads to the creation of a reliable tool for prediction, analysis and interpretation of data for future surveys like LSST. |
