We propose simultaneous XMM-Newton/VLT-UVES observations of the bright ultrafastrotating late-type star AB Dor at X-ray, near UV and optical wavelengths. Weintend to study highly time-resolved correlations of coronal, chromospheric andphotospheric activity phenomena. AB Dor is a unique target in this contextbecause it permits an unprecedented temporal resolution, comparable tostate-of-the-art high-resolution solar spectroscopy. The requirement of strictlysimultaneous observations results from the short-lived nature of the activitysignatures under study.

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.
