Description Evidence for a substantial spectral variability over a time scale of ~months in the X-ray emission of the isolated neutron star RX J0720.4-3125 has been discovered last year by members of our team. It is the first ever detection of such a behavior in one of the seven radio-quiet dim isolated neutron stars discovered by ROSAT. We propose to systematically monitor this source, in order to perform an accurate study of the evolution of the pulse profile and persistent emission.In addition, we propose to search for narrow spectral features with variability timescale shorter, or comparable to, the spin period of this neutron star.

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.
