Abstract	We propose to observe DH Cep and UW CMa, two of the most massive O-star binarysystems in our Galaxy. Both systems are expected to contain a highly radiativewind-wind collision region, and are the ideal complement to the XMM AO1observations of Plaskett.s star (one wind radiative) and HD 159176 (neither windradiative), and to our proposal to observe V444 Cyg, a Wolf-Rayet + O-starsystem. As it appears likely that the wind-wind shock collapses onto the surfaceof the secondary star in UW CMa, DH Cep and UW CMa should have quite differentcolliding wind characteristics. DH Cep is also a member of the young opencluster NGC 7380, and we will conduct a detailed investigation of its populationof X-ray sources.

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.
