Abstract Our main scientific goal is to use the capabilities of XMM/RGS to determine thephysical characteristics of the X-ray emission (during quiescent and flaringstate) of the visual binary 2RE J0241-53. This binary is a strong and veryactive X-ray emitter, classified as a member of an association of Post-T-Tauristars. Its study (in particular in terms of chemical coposition) is importantfor our understanding of the evolution from the T-Tauri phase, and to explainthe origin of the X-ray emission in young stars. A detailed study of any FIPeffect can be perfomed since the photospheric composition of the stars is known.

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.
