|Title||Measuring the Spin-down of The Nearby Isolated Neutron Star RX J0420.0-5022|

|Description||The seven nearest thermally emitting neutron stars may be the best way to sample the true demography of neutron stars, and arguably offer the best prospects for measuring neutron-star radii. Both tasks are limited by our ignorance of their magnetic field strengths, and hence we have been determining timing solutions with Chandra and XMM. The results so far show a surprising grouping of field strengths in a range intermediate between normal pulsars and magnetars, with a hint at an interaction between the thermal emission and magnetic field. Here, we propose to measure the spin-down of RX J0420.0-5022, which has the lowest temperature of the sample and will complete the spin-down measurements for thermally emitting neutron stars with confirmed periodicities.|

|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.
