|Title||X-RAY EMISSION FROM PTT STARS|
|Author||Dr GIULIO DEL ZANNA|
|Description||Our main scientific goal is to use the capabilities of XMM-RGS to determine the physical characteristics of the X-ray emission (during quiescent and flaring state) of the visual binary 2RE J0241-53. This binary is a strong and very active X-ray emitter, classified as a member of an association of Post-T-Tauri stars. Its study (in particular in terms of chemical coposition) is important for our understanding of the evolution from the T-Tauri phase, and to explain the origin of the X-ray emission in young stars. A detailed study of any FIP effect can be perfomed since the photospheric composition of the stars is known.|

|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.
