We propose to obtain EPIC spectra and lightcurves of a sample of 8 youngmagnetic early type stars, four of which were previously detected as X-raysources by ROSAT, and all of which are known to be characterised as non-thermalradio sources. An additional two sources will be used as control subjects sincethese are known to be older A-type stars. Together, this sample provides a rangeof B fields, rotation periods, age and radio fluxes that allow will help us torelate the detected X-ray flux and/or spectrum to the underlying physicalproperties of the confined magnetospheric plasma.

Mission Description
The European Space Agencys (ESA) X-ray Multi-Mirror Mission (XMM-Newton) was launched by an Ariane 504 on December 10th 1999. XMM-Newton is ESAs 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 Earths 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.
