GT- ASCA and ROSAT observations have revealed new compact X-ray sources insupernova remnants which based on the X-ray spectrum and follow-up radio andoptical observations are considered candidates for neutron stars. We proposethe objects in Puppis-A and N157B in the LMC to be deeply observed by XMM inorder to get accurate spectra and photon statistics to search for pulsationsor otherwise temporal changes.

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.
