Abstract
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.

papers that refer to published XMM-Newton results with
complementary observations, follow-up analysis, or theoretical analysis
- CLASS 3:
further deliveries which resulted from the program and which are made
available to the community (e.g. source catalogues, processed images or
spectra in public data base)
- CLASS 4:
