By cross-matching the RASS sources with the Tycho-2 stars, we found a largenumber of extremely X-ray bright and active main-sequence stars.Such extremeX-ray activities have not been fully understood yet. In this proposal, we focuson extremely X-ray bright and active sun-like, G-type, and A-type main-sequencestars for better understanding of stellar dynamo and their evolution from bothobservational and theoretical points of view and propose 5 ks observations for15 targets.

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.
