We propose to obtain high quality coronal spectraof 3 pre-main sequence stars, using the RGS, todetermine their emission measure distributions andcoronal abundances. Together with 3 GTO targets,these stars form a matched grid of cTT, nTT, andZAMS stars to let us study the evolution of coronalproperties from accreting PMS stars through thedevelopment of a radiative core, extending studies ofthe evolution of coronal properties back to ages of1-2 million years.

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.
