Scientific paper

We propose to obtain the first high resolution X-ray spectra of the fastest rotating stars outside of accreting systems: the secondaries of pre-cataclysmic variables that are thought to have undergone common envelope evolution. The resulting data will: (1) Provide C and N abundances with which to perform a definitive test of common envelope evolution theory for pre-cataclysmic binaries; (2) Probe the phenomenon of ``supersaturation'' and coronal morphology, temperature structure and abundances at rotation rates a factor of two greater than studied to date. This coronal activity is responsible for the angular momentum loss that ultimately leads to Roche lobe overflow and accretion.
