We propose a 72 ks EPIC observation of the recently identified young pulsar PSRJ0837-2454. The resulting first-time X-ray spectrum and deep image of thepulsar, complemented by proposed radio observations, will determine whether thispulsar is the first known product of a runaway O/B progenitor star or is amassive neutron star that has been cooled by the fast direct Urca process tobecome one of the coldest young neutron stars known. XMM-Newton affords thenecessary sensitivity and time resolution to measure the spectrum of this faintpulsar and potentially its X-ray pulse profile.

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.
