EUVE Coronal Spectroscopy of the RS CVn Binaries sigma (2) CrB and II Peg

We have used the Extreme Ultraviolet Explorer satellite to study the coronal emission from the EUV-bright RS CVn binaries sigma (2) CrB, observed 1994 Feb 16-21, and II Peg, observed 1993 Oct 1-5. We present time-resolved and integrated EUV short, medium and long wavelength spectra for these binaries. sigma (2) CrB shows significant first-order emission features in the long wavelength region. The coronal emission measure distributions and electron densities are estimated for these active coronae dominated by high temperature (>= 10(7) K) plasma.
