|Title||An X-ray exploration of a wind bowshock from a single star|

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

|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.
