Recent observations of supernova remnants (SNR) with the Spitzer Space Telescoperevealed that thermal dust emission dominates their infrared (IR) spectra. IRemission was detected mostly in X-ray bright SNRs, but it is also present inseveral older and fainter SNRs. We propose an X-ray study of two such IRremnants, 0453.1-66.55 and DEM L204. The origin of IR emission and the nature ofthese SNRs are not understood. X-ray imaging with the XMM-Newton EPIC camerawill reveal location of the hot gas relative to optical and IR emission,allowing us to understand the origin of the IR emission. X-ray spectroscopy willprovide as with temperatures and abundances of the hot gas. We will learn aboutdust content, energetics, and the evolutionary state of these unusual infrared SNRs.

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.
