Description We propose to observe two fast-rotating M dwarfs in the saturated X-ray emission regime with the aim to get information on the characteristic sizes and spatial distribution of the coronal structures, and on the temperature(s) of the emitting plasma. We will achieve the above goal by monitoring the X-ray emission of the targets continuously for three rotation periods, in order to test for the presence of rotational modulation of the coronal emission, and to determine the properties of the emitting plasma by means of X-ray photometry and time-resolved X-ray spectroscopy with EPIC. These observations will yield insights into the nature of the magnetic dynamo (e.g., shell-type, alpha^2-type, turbulent) at work in these stars.

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.
