|Title||A survey of X-ray emission in magnetic Be stars|
|Author||Dr Fabio Favata|
|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.
