Abstract | Evidence is mounting that some OB stars have magnetic fields. Although modest interms of dominating wind flow, they are strong enough to influence the flow. Ourproposal seeks to expand our understanding of shock physics in magnetizedline-driven winds by enlarging the sample of magnetic stars that have beenstudied at X-ray energies. Our study will obtain a total of 85 ksec of EPICspectra for 5 OB stars with detected fields around 100 Gauss to constrain therange of hot plasma temperatures and differential emission measures. |

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. |
