We propose timing observations of the point-like central X-ray source discoveredin the center of a newly identified supernova remnant shell HESS J1731-347 /G353.6-0.7. The source most likely belongs to a yet very small class ofso-called Central Compact Objects (CCOs) - presumably young thermally emittinglow-magnetized neutron stars born in supernova explosions which produced theremnants. Since only a handful of CCOs are currently known any addition to thisclass is highly valuable. With the proposed observation we like to search forexpected but not yet identified pulsations of this putative neutron star.

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.
