RRAT J1819-1458 is a radio-bursting neutron star with a high magnetic field. TheX-ray spectrum detected by Chandra and XMM-Newton is thermal, fit well by ablackbody with kT virgul 0.1 keV with a possible excess at high energies. Theemitting area is consistent with the whole surface of the star. XMM AO5observations reveal a 10 sigma sinusoidal pulsation with 30% pulsed fraction. Werequest 94virgulks on J1819-1458 with aims to: i) perform pulse phase-resolvedspectroscopy, which will allow us to disentangle the emission substructure andmap the magnetic and thermal surface and ii) search for spectral absorptionfeatures, which will provide an independent magnetic field estimate. This willprobe the unusual properties of the RRATs in a way not possible with radio observations.

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.
