Description CCO pulsars are stable rotators with weak dipole B-fields and small spin-down
rates. Old radio pulsars with similar spin parameters as CCOs are never seen to
glitch. However, the CCOs are much younger than their timing ages, and we have
discovered the first CCO glitch, in our X-ray monitoring of 1E 1207.4-5209. CCOs
are theorized to have strong, buried crustal B-fields that will diffuse out in
<1 Myr. The detection of a glitch therefore supports a recent conjecture that
they could be triggered by the diffusion of these strong fields. We propose to
continue timing 1E 1207.4-5209, to verify the unexpected large change in its
post-glitch spin-down rate, and to monitor the CCO in Puppis A for similar
glitches. These observations may allow a first measurement of NS surface magnetic field growth

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.
