We propose to obtain the first high resolution X-ray spectra of the fastestrotating stars outside of accreting systems: the secondaries of pre-cataclysmicvariables that are thought to have undergone common envelope evolution. Theresulting data will: (1) Provide C and N abundances with which to perform adefinitive test of common envelope evolution theory for pre-cataclysmicbinaries; (2) Probe the phenomenon of ..supersaturation. and coronalmorphology, temperature structure and abundances at rotation rates a factor oftwo greater than studied to date. This coronal activity is responsible for theangular momentum loss that ultimately leads to Roche lobe overflow andaccretion.

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.
