We propose to observe a new X-ray bright T-Tauri star in Sco Cen (log10L_x 30.4erg/s). The large flux makes this source a prime XMM-Newton/RGS target. Werequest a 65ks observation of Swift J122825.9-632100 with the RGS on XMM-Newton(50 ks goodtime & 15 ks flaring overhead). The proposed observations will detectthe density and temperature sensitive Helium- like Ne IX and Mg XI triplets andplace a stringent limit on the presence of O VII emission (f_{O VII} 2e-6photons/s/cm^2), providing unique constraints on the accretion flow in thisyoung stellar system.

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.
