Aims. We present a detailed study of the supernova remnant G296.7–0.9 in the 0.2–12 keV X-ray band.
Methods. Using data from XMM-Newton, we performed a spectro-imaging analysis of G296.7–0.9 in order to deduce the basic parameters of the remnant and search for evidence of a young neutron star associated with it.
Results. In X-rays the remnant is characterized by a bright arc located in the south-west direction. Its X-ray spectrum can be best described by an absorbed non-equilibrium collisional plasma model with a column density of NH = 1.24-0.05+0.07 × 1022 cm-2 and a plasma temperature of 6.2-0.8+0.9 million Kelvin. The analysis indicates a remnant age of 5800 to 7600 years and a distance of 9.8-0.7+1.1 kpc. The latter suggests a spatial connection with a close-by HII region. We did not find evidence for the existence of a young neutron star associated with the remnant.
