| Description | Classical T Tauri stars (CTTS) are young, accreting systems. The accretion causes a variable soft X-ray excess and unusual line ratios in the He-like triplets. Accretion signatures can also be seen in optical Doppler images. However, the true correlation of these different signatures only accessible by simultaneous X-ray and ground-based observations has not been studied to date. We propose an 80 ksec XMM-Newton observation covering two full rotations of the CTTS MN Lup; furthermore, we propose simultaneous VLT/UVES spectral observations to obtain a Doppler image of its surface. With its short rotation period and fast rotation, MN Lup is a truly unique target for these observations. |

| 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. |
