| Abstract: | 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.Paper presented at the 11th European Regional Astronomical Meetings of the IAU on  New Windows to the Universe , held 3–8 July, 1989, Tenerife, Canary Islands, Spain. |
