Description Proposed is an XMM-Newton observation of the eclipsing millisecond pulsar J2051-0827 in a 8.6 ks orbital period binary system with a low-mass companion. Optical observations have shown that this system is another example, in addition to PSR B1957+20, of a ..black widow. pulsar, whose relativistic pulsar wind ablates the stellar companion and creates an intrabinary shock. Studying the spectrum and light curve of the X-ray emission from the shocked relativistic wind provides an opportunity to elucidate the properties of the wind and understand the nature of this important class of millisecond pulsars.

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
