We propose to carry out an in-depth X-ray and NUV study of 3 ultra-fast rotatorswith rotation periods between 0.42 and 0.45 days. We intend to study the highlytime-resolved correlation of upper chromospheric and coronal activity indicatorsand to study the rotational modulation of its X-ray and NUV fluxes. Theseproposed observations will allow us to characterize the time-correlated X-rayand NUV emission of stars with saturated coronae. Furthermore, the proposedobservations will yield insight into the nature of the associated magneticdynamos.

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.
