Abstract

We present a numerical simulation carried out in order to explain the complex morphology of the supernova remnant (SNR) 3C 400.2. Numerical simulations were done employing the new yguazu-a code (Raga et al. 2000). In the radio continuum, this remnant seems to be formed by two shells, which are partially overlapping (Dubner et al. 1994). Taking into account observational evidence such as a previous HI study (Giacani et al. 1998), we find that an adequate model for describing the morphology of the SNR 3C 400.2 is obtained by assuming that a single supernova (SN) explosion took place in a dense medium and close to an interface separating this medium from a lower density region. Besides, we also present a new deeper CCD H alpha image mosaic ofthe north-west region of this SNR, which is composed of three single images. From the numerical results, we generated H alpha emission maps, obtaining a good agreement with the observations.
