Recent Measures of CaII H and K Chromospheric Fluxes in a Sample of RS CVn Systems

1990

In this contribution we present the current status of a high resolution H and K spectroscopic survey of RS CVn and BY Dra systems which is being performed at our Department. The reduction and calibration procedures used in the extraction of emission fluxes are analyzed. We discuss the preliminary results for three of the RS CVn systems: HR 5110, Z Her and RT Lac.

Caii H and K spectroscopic observations in active binary systems

1990

We have performed high resolution spectroscopic observations of five active binary systems in the Caii H and K lines at La Palma Observatory. We present the absolute fluxes calculated at the surface of the stars and we discuss the spectral characteristics observed, presence of double emissions and phase variations.
