| Abstract | Central compact objects (CCOs) in supernova remnants (SNRs) represent a largefraction of neutron star births, but are difficult to study because of theirweak magnetic fields. We have measured spin-down dipole fields for only threeCCOs, of which two have spectral features that confirm their weak B-fields. Wepropose deep observations of the two remaining, bright CCOs to search for theirexpected pulsations and cyclotron resonance features that could fall in the softX-ray band. This will help establish the birth properties of an important classof NS, probe their magnetic field structure, and address theories of theirevolution in comparison with ordinary pulsars. |

| 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. |
