Description We propose to obtain a good quality high-resolution X-ray spectrum for the M-type classical T~Tauri star (CTTS) VV~Sco. Our goal is to investigate the characteristics of the X-ray emitting plasma in a star-disk system with a very low mass accreting star. The proposed XMM observation will allow us to test different scenarios proposed to explain accretion-driven X-rays in pre-main-sequence stars, and hence to improve our understanding of the mechanisms and physical conditions which regulate the accretion process in CTTSs and its possible influence on the coronal emission.

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.
