Abstract (from CDS):

We present an analysis of the spectra of the star V837 Tau, which belongs to a class of chromosphere-active RSCVn type stars. The observational material was obtained with the 1.5-m Russian-Turkish telescope RTT-150 and the 2.6-m Shajn telescope of the Crimean astrophysical observatory. To reveal signs of the photosphere spottedness of the primary and to isolate the faint secondary, we performed the deconvolution of the "averaged" spectral profile of the system. By describing the radial velocity curves, we refined the orbital elements of the binary system, and by modeling spectrawe determined the fundamental parameters of the components, as well as the chemical composition of the atmosphere of the bright component. Using the Doppler mapping method we reconstructed the distribution of spots on the surface of the bright star. We show that the spots are concentrated in a belt at medium (about 40 deg.) latitudes. The hydrogen line profiles have a variable emission feature in the bright component, and the H_alpha line exhibits traces of chromospheric activity in the secondary.
