Abstract
Spatially resolved spectroscopy of the supernova remnant PKS 1209–52 and the point source within it is presented, based on observations made with the EXOSAT PSD detector. We find evidence that the shock front of the supernova remnant is interacting with an interstellar cloud. The data further indicate that the whole remnant is not in pressure equilibrium. The average PSD spectrum of the SNR is fitted with a Raymond & Smith line-emission model: the best-fit temperature is |$1.7\times{10}^{6}\,\text{K}$| and the absorbing column is |$1.4\times{10}^{21}\,\text{cm}^{-2}$|⁠. The spectrum of the point source is harder than that of the supernova remnant, but requires a similar absorbing column. We suggest that this source is the neutron star remnant of the supernova explosion.
