Description We propose to observe two young fast rotating stars observed with ROSAT in the
supersaturation regime. We aim at detecting rotational modulation in their X-ray
emission as recently found for VXR45, a star with similar rotational properties
observed by us with XMM/Newton. If rotational modulation is a general
characteristic of supersaturated stars, we will be able to determine the
presence of an asymmetric distribution of coronal structures in such stars and
from their (or lack of) spectral variations, to infer the characteristics of
such structures constraining the properties of the underlying dynamo.

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.
