|Title||Probing the magnetic confinement of the winds of Oe stars|
|Author||Dr Yael Naze|
|Description||The small group of Oe stars are usually considered as the hot analogs of the Be-type objects. A possible explanation for their equatorial outflow is that their stellar wind is magnetically channeled towards the equator, where it forms a circumstellar disk. A magnetic signature is best unveiled in the high-energy domain. We therefore request observations of the three brightest Oe stars, HD45314, HD60848 and HD155806, for 20ks each in order to pinpoint the origin of their Oe characteristics.|

|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.
