|Title||The X-ray emission mechanism in magnetic Be stars|
|Author||Dr Fabio Favata|
|Description||We propose to obtain RGS spectra and EPIC light curves and spectra of the magnetic Be star beta Cep, to provide stringent tests of the magnetically confined wind shock model proposed to explain the X-ray emission observed from this star. Measurement of the density from the O VII triplet (as well as of the Ne and Mg triplets), of the line broadening, and determination of the rotational modulation of the spectral characteristics will allow to discriminate X-ray emission due to this novel mechanism from either coronal emission or emission due to the shocked winds observed in non-magnetic high-mass stars.|

|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.
