Supernova remnant G296.7-0.9 in X-rays.

PRINZ T. and BECKER W.

Abstract (from CDS):

We present a detailed study of the supernova remnant G296.7-0.9 in the 0.2-12keV X-ray band. 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. 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+0.07x1022cm–2 and a plasma temperature of 6.2+0.9–0.8 million Kelvin. The analysis indicates a remnant age of 5800 to 7600 years and a distance of 9.8–0.7+1.1kpc. 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.
