Description Discovering the pulsar in the Cas A supernova remnant is the key to confirming the interpretation of the Central Compact Objects (CCOs) as a major class of neutron stars (NS) that are born spinning slowly (P gt 100 ms) and with surprisingly weak magnetic fields (B lt 1.e11 G). Mounting evidence for such a population has overtaken the previous hypothesis for the Cas A CCO as a magnetar in quiescence. XMM can make the definitive search for pulsations from this, the youngest known NS. A pulsar in Cas A will reveal the spin period and dipole B-field of a NS at an age that is only a few percent of the known magnetars and CCOs. It will address the relationship between initial angular momentum and natal magnetic field, and investigate their role in the evolution of young NSs.

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.
