Description 1E 1207.4-5209, the central compact object in the SNR PKS 1209-51-52, shows absorption lines in its thermal X-ray spectrum and 424 ms pulsations. The phase-coherent timing of 14 XMM-Newton and Chandra observations of 2000-2005 resulted in two timing solutions with different signs and very small magnitudes of period derivative. The spin-down solution suggests that 1E1207 is a neutron star born with a rather low magnetic field and almost the same period as that currently observed. The spin-up solution could be explained by a low-rate accretion from a supernova debris disk. To find the unique timing solution and understand the properties of this enigmatic object, we propose new timing observations, which will be phase-connected with all the previous observations.

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.
