English: A comparison between an observed image (left panel; X-ray image (XMM) and IR contours (WISE)) and schematic picture of IRAS 00500+6713 (right panel). The schematic picture includes the morphology of IRAS 00500+6713 inferred from multiwavelength observations (the left semicircle) and our dynamical model (the right semicircle). A dusty IR ring is sandwiched by the inner and outer X-ray nebulae. We assume that the inner X-ray nebula corresponds to the wind termination shock while the outer X-ray nebula to the shocked interface between the ejecta of SN 1181 and the ISM, and the dust ring corresponds to the unshocked SN ejecta.
