|Title||Possible Magnetic Field Break-out in the Neutron Star CCO 1E 1207.4-5209|
|Author||Dr Eric Gotthelf|
|Description||The CCO pulsar 1E 1207.4-5209 has been an extremely stable rotator, with a weak B-field and a small spin-down rate that has remained constant to <1% over 15 years. It is a unique NS whose B-field is measured as virgul9E10 G, both spectroscopically and through timing. Yet the properties of CCO pulsars cannot be explained unless they have strong crustal magnetic fields, perhaps buried by SN fall-back material. We have just identified a glitch-like event that may indicate changes in the B-field configuration of 1E 1207.4-5209, evidence of the field diffusing or breaking through the crust, or possibly torque noise due to low-level accretion from a hypothetical fall-back disk. We propose a renewed XMM-Newton campaign to follow the spectral and timing evolution of this remarkable object.|

|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.
