Our analysis of a short Chandra ACIS observation of PSR J1740+1000 has shownthat it is a bright X-ray source with the spectrum dominated by thermalemission. The spectrum fits best with a two-component blackbody model althoughthe presence of an additional power-law component is not excluded by the currentdata. Pulsations at the radio period of 154 ms are detected at a 3-sigma level.We propose an observation of this middle-aged (100 kyr) pulsar with EPIC toaccurately measure its spectrum and pulse profile and perform phase-resolvedspectroscopy and energy-resolved timing. This would unambiguously establish thenature and orgins of the pulsar.s spectral components and add to ourunderstanding of the neutron star properties and evolution.

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.
