Description The issue of the X-ray emission from Wolf-Rayet (WR) stars is far from being elucidated. Thanks to previous observations, we know indeed that even though several WN-type WR are detected in X-rays, it appears that single WC stars are not detected, most probably because of the strong opacity of the stellar wind. However, significant X-ray emission is expected if WC stars are part of a colliding-wind binary system. In the case of dust-making WR stars (WC-type with dense stellar winds), dust is most probably produced in a wind-wind interaction region. Performed and forthcoming interferometric observations in the near-infrared (VLTI, PI: De Becker) will help us to investigate the multiplicity of WR106.(abridged)

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.
