Description We propose to observe the original eclipsing binary millisecond radio pulsar B1957+20 at high time resolution in order to determine the origins of the known X-ray flux from the system. These observations will detect the pulsed magnetospheric emission that is certainly produced by this energetic pulsar and allow us to determine the fraction of the total X-ray flux that it represents. Additionally, the detection of modulation of the pulsed and-or unpulsed X-ray flux as a function of the 9 hr orbital period will enable us to determine what (if any) emission results from the intra-binary shock (from the collision of pulsar and companion winds) and-or the pulsar bow shock (from the interaction of the pulsar wind with the ISM).

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.
