| Description | The investigation of massive colliding-wind binaries offers the opportunity toprobe stimulating physical processes, including copious X-ray emission andparticle acceleration. Among the massive systems known accelerate particles,HD167971 is of particular interest in the sense that it is a quite long periodsystem (about 21 years) whose wind-wind interaction is a powerful thermal (inX-rays) and non-thermal (in radio) emitter, despite the significant geometricaldilution of the wind outflows due to the rather large stellar separation. Thisfact makes HD167971 the longest period massive system accelerating particleswhose X-ray emission is easily accessible with present observatories. The aim isto pursue its X-ray study in light of new crucial information about its orbit. |

| 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. |
