Abstract	Classical T Tauri stars (CTTS) are young, accreting systems. The accretion isthought to cause a soft X-ray excess and unusual line ratios in the He-liketriplets. The accretion spots can also be seen with optical Doppler-imaging;however, the final test to correlate these signatures - simultaneous X-ray andground-based observations - is still missing. We propose a 15 ks pilot study ofMN Lup, the prime target for simultaneous observations from the optical point ofview, to confirm its CTTS status and characterize its X-ray properties.

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.
