Description We propose simultaneous observations of the ultrafast rotating late-type star Speedy Mic at X-ray, near UV and optical wavelengths. In this way we want to study the spatial correlation of coronal, chromospheric and photospheric activity phenomena. The proposed study includes time-resolved high resolution spectroscopy monitoring of key line ratios, probing the distribution of coronal temperatures, densities and elemental abundances.The requirement of strictly simultaneous observations results from the short-lived nature of active regions on Speedy Mic. Our proposal is based on our previous results from VLT measurements constructing a Doppler image of Speedy Mic and finding pronounced rotational modulation of CaII emission.

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.
