Scientific paper
We propose to perform a single observation (50 ks) of the mixed-morphology supernova remnant Kes 69. Recent millimeter-wavelength observations proved that Kes 69 is interacting with a molecular cloud and X-ray emitting knots have been observed in the interaction region with ROSAT. Clumps of SNR ejecta moving in a dense cloud are predicted to produce a non-thermal knotty emission characterized by strong lines. This effect has been observed only in IC 443 and with the ROSAT dara it is not possible to perform a spatially resolved spectral analysis on the knots in Kes 69. We aim at studying the physical conditions of the plasma in the interaction region. We will also study the inner part of the remnant to investigate the presence of ejecta, recently detected in other mixed-morphology SNRs.
