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.
