The atmosphere of the supergiant 6 Cas. IV. The spectrum and radial velocities of the visual companion.
Abstract
Community of origin for the components A and B of the multiple system 6 Cas - ADS 17022 is determined. The numerical spectral classification of the spectrograms, obtained by the main stellar spectrograph of the 6-m telescope has been made; for 6 Cas B: Sp = 09.75±0.1, Mv = -5m8±0m2. Radial velocities of 6 Cas B are determined; maximum and minimum vr values are -28 and -98 km/s. 6 Cas B is a spectral double star. A list of the wavelengths for Xe II lines in the blue spectrum range is given in the supplement; the measurement errors are ±0.01 Å.
