Abstract Two of the strongly absorbed super-giant HMXB discovered by INTEGRAL areeclipsing systems. This very rare property allows a comprehensive study of thedynamics and of the stellar winds in those systems. The aim of this proposal isto obtain quantitative constraints on the ionisation, density and clumping ofthe stellar wind along the orbit and to measure the masses of the neutron stars.

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.
