The Supernova Remnant G296.7-0.9 in X-rays
Abstract
Aims: We present a detailed study of the supernova remnant (SNR) 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 to 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 best be described by an absorbed non-equilibrium collisional plasma model with a hydrogen density of NH=1.24-0.05+0.07 x 1022 cm-2 and a plasma temperature of 6.2+0.9-0.8 million Kelvin. The analysis revealed 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 a young neutron star associated with the remnant.
