Description We propose to carry out an in-depth X-ray and NUV study of 3 ultra-fast rotators
with rotation periods between 0.42 and 0.45 days. We intend to study the highly
time-resolved correlation of upper chromospheric and coronal activity indicators
and to study the rotational modulation of its X-ray and NUV fluxes. These
proposed observations will allow us to characterize the time-correlated X-ray
and NUV emission of stars with saturated coronae. Furthermore, the proposed
observations will yield insight into the nature of the associated magnetic
dynamos.

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.
