The runaway O-type binary HD 14633 was likely ejected from the cluster of itsbirth by dynamical interactions in the dense environment. Recent XMM-Newtonobservations have detected a soft, nonthermal X-ray flux that likely originatesin a colliding wind shock region in the binary. The large variation in systemseparation between periastron and apastron will contribute to X-ray flux andspectral variability during the orbit. We propose observations with XMM-Newtonthat will measure the variable intra-system absorption, probe the geometry andphysical parameters of the wind shock region, and investigate abundanceanomalies in the HD 14633 binary system.

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.
