    AB Doradus is a rapidly rotating southern K1 star known to be highly
    active at X--ray, UV and radio wavelengths. We propose observations
    with ASCA to study the X-ray line spectrum of AB Doradus and to
    search for a nonthermal component in the higher-energy (above 2 keV)
    X-ray emission.  Using EUV data acquired with the Extreme Ultraviolet
    Explorer satellite, we will fit the EUV and X-ray spectra, both at
    high spectral resolution, simultaneously against thermal models to
    determine the distribution of temperatures in the corona of this
    star.
