|Title||Measuring the Spin-Down and Magnetic Field Strength of the CCO Pulsar in PuppisA|
|Author||Prof Jules Halpern|
|Description||This proposal is the second element of our two-year plan to measure the spin-down rate of the pulsar in Puppis A by obtaining a phase-coherent timing solution. If it is a weakly magnetized neutron star like the other CCO pulsars, this is the only practical way of measuring its spin-down. Our sensitivity to P-dot will correspond to a surface dipole B-field as small as 3.e10 G, comparable to our measured value for the CCO pulsar PSR J1852+0040 in Kes 79. Such a result would provide important support for the "anti-magnetar" model of CCOs. In addition, we will explore possible reasons for the unexplained surface hot spots using the energy-dependent pulse profiles and phase-resolved spectra.|

|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.
