Abstract	In an eccentric massive binary, the X-ray emission of an adiabatic windinteraction should vary as 1/d. Yet, among the few adiabatic colliding wind O +O binaries observed so far, deviations from this relation were found. Sincethese systems are non-thermal radio emitters, such deviations could reflect theimpact of modified shocks. To test this explanation, we propose to collect anX-ray spectrum of the 558 day period O-star binary HD54662 near apastron.HD54662 should feature an adiabatic wind-wind interaction, but shows no evidencefor the presence of relativistic particles. Together with an existingobservation near periastron, these data will provide a clean test of the impactof non-thermal particles on the shocks.

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.
