Title Exploring Connections between Magnetism and X-ray Emission in Massive Stars

Author Prof Richard Ignace
Description Evidence is mounting that some OB stars have magnetic fields. Although modest in terms of dominating wind flow, they are strong enough to influence the flow. Our proposal seeks to expand our understanding of shock physics in magnetized line-driven winds by enlarging the sample of magnetic stars that have been studied at X-ray energies. Our study will obtain a total of 85 ksec of EPIC spectra for 5 OB stars with detected fields around 100 Gauss to constrain the range of hot plasma temperatures and differential emission measures.

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.
