Abstract GT- HD 93403 is an eccentric (e=0.52) spectroscopic binary of spectral typeO5(f) + O7III with an orbital period of 15.09 days situated within the HIIregion around Eta Carinae. From the X-ray light curve of a colliding windsbinary system we can constrain the mass loss rates of the two stars andinvestigate the hydrodynamical properties of their winds.

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.
