Modeling the X‐rays from SNe 1993J & 1998S

• TheX-ray emission from the Type II supernovae SNe 1993J and1998S is modelled using the numerical code described in Nymarket al. (2006), assuming that most of the observed X-ray emissioncomes from the reverse shock created by the interaction betweenthe supernova ejecta and a dense circumstellar medium. We findthat the spectra of both SNe are compatible with aCNO-enriched composition. For SN 1998S we find evidence for acomponent from both the reverse and forward shock, while theX-ray flux for SN 1993J is dominated by the reverseshock.
