Title XMM-Newton observations of WR140 through periastron passage

Description WR40 is the archetypal long period WR+O colliding wind binary (CWB) system, where the wind from the WR star collides with the wind of its massive companion. Its X-ray brightness, giant IR outbursts, and distinctive non-thermal radio lightcurve are all attributed to the wind-wind collision region (WCR), the properties of which dramatically change due to the exceptionally high orbital eccentricity (e > 0.88). XMM-Newton observations through periastron passage will provide data to determine the key parameters of this system and the physical processes occuring at the WCR. Detailed modelling of the 3D hydrodynamics and the emission and absorption processes occuring within the WCR and stellar wind envelopes, and spanning the radio to TeV domains, will underpin our data analysis.

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.
