Title XMM follow-up of the massive particle accelerator HD167971: half a period after!

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

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.
