Excess Hα emission in chromospherically active binaries: the spectroscopic survey.

MONTES D., FERNANDEZ-FIGUEROA M.J., DE CASTRO E. and CORNIDE M.

Abstract (from CDS):

We present new spectroscopic Hα observations for a sample of 24 chromospherically active binary systems (RS CVn and BY Dra classes), of different activity levels. By using the spectral subtraction technique (subtraction of a synthesized stellar spectrum constructed from reference stars of similar spectral type and luminosity class) we obtain the active-chromosphere contribution to the Hα line. The Hα emissions arising from each individual star were obtained when it was possible to deblend the contribution of both components.
