Abstract [en]

The X-ray emission from the Type II supernovae SNe 1993J and 1998S is modelled using the numerical code described in Nymark et al. (2006), assuming that most of the observed Xray emission comes from the reverse shock created by the interaction between the supernova ejecta and a dense circumstellar medium. We find that the spectra of both SNe are compatible with a CNO-enriched composition. For SN 1998S we find evidence for a component from both the reverse and forward shocks while the X-ray flux for SN 1993J is dominated by the reverse shock.
