| Abstract | The CCO pulsar 1E 1207.4-5209 has been an extremely stable rotator, with a weakB-field and a small spin-down rate that has remained constant to <1% over 15years. It is a unique NS whose B-field is measured as ~9E10 G, bothspectroscopically and through timing. Yet the properties of CCO pulsars cannotbe explained unless they have strong crustal magnetic fields, perhaps buried bySN fall-back material. We have just identified a glitch-like event that mayindicate changes in the B-field configuration of 1E 1207.4-5209, evidence of thefield diffusing or breaking through the crust, or possibly torque noise due tolow-level accretion from a hypothetical fall-back disk. We propose a renewedXMM-Newton campaign to follow the spectral and timing evolution of this remarkable object. |

| Mission Description | The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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. |
