Multiwavelength optical observations of the chromospherically active binary system OU Gem
A. Latorre, D. Montes, M. J. Fernandez-Figueroa
We have analysed several multiwavelength optical observations (H_alpha, H_beta, H_epsilon, Ca II H & K, Ca II IRT lines) of chromospherically active binary system OU Gem, taken in…

Multiwavelength optical observations of the chromospherically active binary system MS Ser
J. Sanz-Forcada, D. Montes, M. J. Fernandez-Figueroa +2
We present here a continuation of our ongoing project of multiwavelength optical observations aimed at studying the chromosphere of active binary systems using the information prov…

Application of the spectral subtraction technique to the CaII H & K and H lines in a sample of chromospherically active binaries
D. Montes, E. De Castro, M. J. Fernandez-Figueroa +1
We present new spectroscopic observations in the Ca~{\sc ii} H \& K line region for a sample of 28 chromospherically active binary systems (RSCVn and BYDra classes), with dif…
