Abstract We propose to observe the very active BY Dra star Gl355 (LQ Hya). Our goalis to study the detailed individual elemental abundances in its corona. TheXMM-Newton instruments are perfectly suitable for this purpose since itssuperior spectral resolution allows forabundance determinations of many individual elements. Themetal abundances in the coronae of Gl355 will be compared element by elementto the abundances in the photosphere previously obtained byhigh-resolution optical spectroscopy. Our aim is to better understand thephysical mechanisms driving the lack of metallicity in the corona of somelate-type active stars, such as Gl355, with respect to the photosphere.

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.
