| Abstract: |
We compare parameters of well-observed type II SN1999em derived by M. Hamuy and D. Nadyozhin based on Litvinova & Nadezhin (1985) analytic fits with those found from the simulations using our radiative hydro code stella. The same code applied to models of SN1993J allows us to estimate systematic errors of extracting foreground extinction toward SN1993J suggested by Clocchiatti et al. (1995) which is based on the assumption of black body radiation of the supernova envelope near the first maximum light after shock break out. A new implicit two-temperature hydro code code supremna is introduced which self-consistently takes into account the kinetics of ionization, electron thermal conduction, and radiative losses. Finally, a combination of stella and supremna allows us to use the same Type Ia supernova (SNIa) models both for building their light curves and predicting X-ray spectra of young Supernova remnants such as Tycho and Kepler. For the comparison of theoretical results with the observations we used data on Tycho supernova remnant (SNR) obtained with XMM—Newton space telescope. |
