Description We propose to obtain high quality coronal spectra of 3 pre-main sequence stars, using the RGS, to determine their emission measure distributions and coronal abundances. Together with 3 GTO targets, these stars form a matched grid of cTT, nTT, and ZAMS stars to let us study the evolution of coronal properties from accreting PMS stars through the development of a radiative core, extending studies of the evolution of coronal properties back to ages of 1-2 million years.

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.
