Description Central compact objects (CCOs) in supernova remnants (SNRs) represent a large fraction of neutron star births, but are difficult to study because of their weak magnetic fields. We have measured spin-down dipole fields for only three CCOs, of which two have spectral features that confirm their weak B-fields. In AO12, we proposed deep observations of the two remaining bright CCOs to search for their expected pulsations, and were given one A and one C target. Here we repropose the second target for AO13, and request a followup observation of the first target to confirm a possible period that was found in the AO12 observation. This program will establish the birth properties of an important class of NS, probe their magnetic field structure, and address pulsar evolution.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
