| Abstract | We propose to observe the original eclipsing binary millisecond radio pulsarB1957+20 at high time resolution in order to determine the origins of the knownX-ray flux from the system. These observations will detect the pulsedmagnetospheric emission that is certainly produced by this energetic pulsar andallow 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-rayflux 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 ofpulsar and companion winds) and/or the pulsar bow shock (from the interaction ofthe pulsar wind with the ISM). |

| 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. |
