Abstract BD+43 3654 is a very massive runaway star likely formed in the central region ofCygnus OB2 association. The interaction of its strong wind with the localinterstellar medium has produced a bow shock that has been detected at theinfrared with the MSX. Multifrequency VLA observations carried out by us show aradio structure clearly correlated with the MSX bow shock and a non-thermalcomponent located at the infrared emission peak position. This indicates that arelativistic population of electrons is present in the shock. This particlepopulation can produce a non-thermal X-ray component, in addition to the thermalcomponent associated with the shocked gas. We propose to detect for the firsttime the X-ray emission from the bow shock produced by a runaway young hot star.

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.
