Abstract We propose a follow-up of a short GT observation of 1E1048.1-5937 in which significant spectral variations as a functionof the pulse phase and possible spectral lines were detected.Significant and relatively broad proton cyclotron featuresare predicted by model atmosphere calculations for magnetars.A detailed phase resolved spectroscopy of this AnomalousX-ray Pulsar (the one with the largest pulse fraction)can provide important information to discriminate betweenmodels based on accretion onto isolated neutron stars and thoseinvoking thermal emission from the surface of a magnetar.

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.
