Mixed-morphology (MM) SNRs represent SN explosion in wind-blown bubbles. Theyare thus good places to study the interaction between massive stellar winds,SNRs, and the surrounding ISM. We propose a 50ks XMM-Newton observation of apeculiar MM SNR, Kes 27. We will map out the spectral parameters in tessellatedmeshes and construct EW maps of some emission lines with our newly developedspatially-resolved spectroscopy method. These analyses will help us tounderstand the unusual properties of this MM SNR, such as the X-ray bright outershell, shell-like interior, and strong NE-SW asymmetry in morphology. We willalso search for evidence of over-ionization state plasma and coherent X-rayfeatures associated with the shell of the HI cavity.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs second cornerstone of the Horizon 2000 Science Programme. It carries 3 high throughput X-ray telescopes with an unprecedented effective area, and an optical monitor, the first flown on a X-ray observatory. The large collecting area and ability to make long uninterrupted exposures provide highly sensitive observations. Since Earths atmosphere blocks out all X-rays, only a telescope in space can detect and study celestial X-ray sources. The XMM-Newton mission is helping scientists to solve a number of cosmic mysteries, ranging from the enigmatic black holes to the origins of the Universe itself. Observing time on XMM-Newton is being made available to the scientific community, applying for observational periods on a competitive basis.
