dc.description© European Southern Observatory. © EDP Sciencies The Isaac Newton Telescope, on the island of La Palma, is operated by the Royal Greenwich Observatory at the Spanish Observatorio del Roque de los Muchachos of the Instituto de Astrofísica de Canarias. We are grateful to the VILSPA staff for the use of their facil­ities. We thank Dr. R. González Riestra and Dr. J. Zamorano for help with IHAP use. The authors are indebted to an anonymous referee for his critical reading of the manuscript and valuable comments. This work has been supported by the Spanish Comisión Asesora de Investigación Científica y Técnica (CAICYT No. 2254/83).
dc.description.abstractWe report here new Ca II H and K emission line fluxes and equivalent widths for seven RSCVn binary systems, observed at several orbital phases. All the stars show enhanced chromospheric activity. With information from available spectra, an in­ dividual study for each star has been done. Double emission has been found for some systems in which perhaps the hotter compo­nent could be the more active. We have tested spectroscopically the model of localized active regions for the prototype RSCVn.
