CA II H and K emissions in binaries. II. G and K type giants.
Abstract
An analysis of intensities of Ca II emission K-line is made for 44 binaries with known orbital elements. Correlations between K line intensity and tidal interactions are found. Possible mechanisms of intensification of chromospheric activity due to tidal interaction between the components are presented.
