dc.descriptionSN 2002ic is a unique supernova which shows the typical spectral features of Type Ia supernovae (SNe Ia) near maximum light, but also apparent hydrogen features that have been absent in SNe Ia. We have calculated hydrodynamical models for the interaction between the SN Ia ejecta and the H-rich circumstellar medium (CSM) to reproduce the observed features of SN 2002ic. Based on our modeling, we suggest that CSM is aspherical (or highly clumpy) and contains about 4-5 solar masses. Possible progenitor systems of SN 2002ic are discussed.
