| Abstract | 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. |
