| 1st Abstract | Type Ia supernovae (SNe Ia) are believed to result from the thermonuclear explosion of carbon oxygen white dwarfs. However, the exact nature of their progenitor systems remains illusive. One of the key tools to determine/eliminate the origin of SNe Ia is the study of their interaction of with circumstellar structures formed by the mass outflows of the progenitor system. In this work we present the case where a SN Ia occurs in the center of a planetary nebula (PN). We preform 2D hydrodynamic simulations and we study the results of a SN Ia – PN interaction on the morphological, kinematical and emission properties of the resulting supernova remnant (SNR). We compare the results of our simulations with the properties of historical SNRs -resulted from SNe Ia-which show evidence of interaction with circumstellar structures e.g. Kepler’s SNR. Finally we discuss whether the scenario of a SNR Ia-PN interaction is aligned to the current properties/limitations of the circumstellar medium around SNe Ia imposed by observations. |
