| 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. |
