Title A survey of X-ray emission in magnetic Be stars

Description We propose to perform a survey of the X-ray emission from Be stars, of both the magnetic and non-magnetic variety. Remarkably, only two Be stars (apart from the very peculiar gamma Cas variety) have been observed in X-rays in recent times (beta Cep and lambda Eri), with very interesting results; no other Be star has been observed in X-rays in the post-ROSAT era. The present survey is thus needed to bring the study of X-ray emission from Be stars, with the attending interesting physics of shocked winds (either magnetically confined or not) and decretion disks into the modern era.

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.
