High resolution X-ray spectroscopy of young stellar objects clearly indicatesthat in classical TvirgulTauri stars the physical properties of the cooler X-rayemitting plasma are strongly influenced by accretion and outflow processes. Thedetailed characteristics apparently depend on stellar parameters like mass andradius; however, especially low mass stars are missing in the the existing X-raydata of young, accreting stars. The proposed observation of DN Tau will extendthe current sample into the mass regime of M dwarf precursors and intends toderive a more comprehensive picture of the pre-main sequence evolution of lowmass stars.

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.
