dc.descriptionSupernova remnants are usually analysed in the light of hydrodynamical models of the interaction of supernova ejecta with either a constant density ambient medium or a circumstellar medium produced by a constant presupernova wind. However, the ejection of energetic wind during the presupernova phase changes the ambient medium structure and, consequently, the early supernova remnant evolution. We have analysed the evolution of young remnants of type Ia supernovae, focusing on the imprint of the presupernova wind history on the supernova remnant structure and on the influence of the explosion mechanism. We have found that the remnant evolution is most sensitive to the explosion mechanism at ages not larger than a few hundred years, while the presupernova history shows its influence at later epochs, before the Sedov phase sets in.
