Only about ten Central Compact Objects (CCOs), a peculiar manifestation ofisolated neutron stars (NS) associated with young supernova remnants (SNRs),have been detected in X-rays. This is too few to address fundamental questionssuch as the equation of state of degenerate NS matter. Some evidence onsuperfluidity of this matter has been obtained from the observations of the CCOin Cas A. To expand this sample we selected four Galactic SNRs which either havenot been properly studied or not observed in X-rays, but which have similarparameters as SNRs with CCOs. We propose to firmly identify these SNRs in X-raysand using the high spatial resolution of XMM-Newton to search for CCOs possibleassociated with these 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.
