|Title||Accretion-driven X-rays from low-mass classical T Tauri stars|
|Author||Dr Antonio Maggio|
|Description||We propose to obtain a good quality high-resolution X-ray spectrum for the M-type classical TvirgulTauri star (CTTS) VVvirgulSco. 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.
