Abstract

Spectrophotometric observations of the RS CVn binary system V711 Tau (HR 1099), convering the wavelength interval λλ3300–7100 Å, have been presented. A comparison of the standard spectral scans of V711 Tau with the spectral scans of the stars of known spectral types and luminosity classes taken from the Breger (1976) catalogue shows that, at all phases shown in the diagram, the spectral-luminosity type of the star is K0IV or K0III. The magnitude of the system fluctuates from 5m.71 to 5m.79 average being 5m.75 approximately, the faintest being near 0p.43 and the brightest near 0p.78. The region around Balmer jump and near Hα region is apparently variable.
