We propose a deep XMM-Newton campaign to observe PSR J0250+5854, a radio pulsarwith the longest spin period known at 23.5 s. The rotational parameters of thepulsar suggest that it could be related to the X- ray Dim Isolated Neutron Stars(XDINSs), which are believed to be descendants of magnetars. The observationswill constrain the thermal emission of PSR J0250+5854 down to the properties ofthe faintest XDINS known. If any X-ray emission is detected, this will be thefirst radio emitting XDINS, unifying the two different manifestations of neutronstars.

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.
