Abstract | Massive stars ejected from their birth place, the so-called runaway massivestars, are likely to produce strong bow shocks through the interaction of thetheir stellar winds with the interstellar medium. Such shocks have been provento be efficient at accelerating particles, as revealed by the identification ofnon-thermal radiation in a couple of objects. This large programme aims atobtaining measurements of the non-thermal X-ray flux of a carefully selectedsample of bow shock runaways (BSRs), to quantify their capability to accelerateparticles, in relation with their potential contribution to the production ofGalactic cosmic-rays. Such an unprecedented collection of data is aimed atconstituting some kind of legacy programme for XMM-Newton, before the advent of future generation X-ray observatories. |

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. |
