Description GT- WR 40 (=HD 96548) is a Wolf Rayet star of spectral type WN8 located rather far away from the Galactic plane. Its spectrum is variable (Moffat & Isserstedt 1980) and particularly rich in emission lines and P Cygni profiles. The UV lines exhibit changes that are interpreted by Smith et al. (1985) as signs of a shocked stellar wind flow. The star is surrounded by the axisymmetric ring nebula RCW 58 which is classified as containing stellar ejecta, an almost unique feature for such a late-type WN star.Ring nebulae offer also the opportunity to look for the X-ray signature of the interaction of the high speed ejected material with the interstellar matter.

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.
