Scientific paper

With this proposal we seek to obtain ACIS-S spectra of two central stars of planetary nebula, known to have post-common envelope central stars with main sequence companions. We expect these companions to have been spun up during the common envelope and to have X-ray bright cornoae as a result. These detections will establish the X-rays as a way of detecting M-type main sequence companions to central stars, which are hard to detect with other methods. The Lx and Tx will be compared to prediction from models and will be used to carry out a first determination of the amount of mass and angular momentum accreted during the common envelope.
