Abstract

We have investigated the X-ray emission from the shock-heated plasma of the Galactic supernova remnant Kesteven 69 with XMM-Newton. Assuming the plasma is at collisional ionization equilibrium, a plasma temperature and a column absorption are found to be kT ~ 0.62 keV and $N_H{\sim}2.85{\times}10^{22}\;cm^{-2}$ respectively by imaging spectroscopy. Together with the deduced emission measure, we place constraints on its Sedov parameters.
