Description We propose to gather XMM observations of two selected early-type colliding
winds binaries (Plaskett.s Star & HD159176). The resultant exposures will
provide high quality EPIC and RGS spectra which will be used to constrain
the mass loss rates of the stars, to investigate the effects of various
hydrodynamical processes and to study the chemical abundances of the stellar
winds. Furthermore, the EPIC observations will enable us, for the first time,
to seek for the predicted dynamical instabilities of the wind interaction
region which should lead to strong variability of the X-ray flux on time scales
of 30 minutes. Our results should improve our understanding of the mass loss
mechanism of massive stars and ultimately help to understand their

Mission Description The European Space Agency's (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESA's 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 Earth's 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.
