  Short-period binaries represent extreme cases in the generation of stellar
coronae via a rotational dynamo. Such stars are important for probing the
origin and nature of coronae in the regimes of rapid rotation and activity
saturation. VW Cep (P=0.28 d) is relatively bright, partially eclipsing, and
very active object. We present preliminary results from Chandra X-ray
spectroscopy with the High Energy Transmission Grating. Light curves show
flaring and rotational modulation, but no strong eclipses. Emission lines are
broader than instrumental, indicating emission from both binary components.
Velocity modulation of emission lines is indicative of geometric structure of
the emitting plasma. The emission measure shows a broad range of temperatures
and strong peak.
