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

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.
