Abstract | The recent detection of magnetic fields in massive stars has profoundly changedour understanding of the structure and evolution of these objects. In addition,detailed modelling shows that intense magnetic fields can have a strong impacton the X-ray emission. Currently, only a few tens of magnetic hot stars areknown, and much fewer have been observed at high energies. The observeddiversity of behaviours and the small sample size actually prevent us fromrecognizing the overall trends. By doubling the sample size with a smallinvestment of time, we will be able to undertake such a systematic study of theX-ray properties of magnetic massive stars, which will help us better understandwhich parameters govern their high-energy emission. |

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. |
