| Abstract | We are proposing to use the eclipses of the X-ray source X2127+119 to probe thestructure of X-ray binaries. We have chosen this source because it has severalunique advantages, including a well determined distance, metallicity, andfavorable optical magnitude. However, the results from the study should beapplicable to all X-ray binaries. We have already been allocated 18 HST orbitsfor this study, which will allow us to determine the structure of the outer discand wind, and are applying here for the data which will determine the nature ofthe X-ray emitting regions, especially inner disc and accretion disc corona. |

| 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. |
