We propose to observe two low-activity super-metal-rich (SMR) late-type stars,in order to determine the individual element abundances and the plasma emission measure distribution vs. temperature, from the joint analysis of EPIC and RGS spectra. The XMM observations of these peculiar targets will help to testcurrent hypotheses about the dependence of the element fractionationmechanism(s) in corona on the stellar magnetic activity level.

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.
