- Abstract
The results of investigations of the H and H lines in the spectrum of the star HD 206267 are presented. Observations were carried out in 2011-2014 at the Cassegrain focus of the 2-m telescope of the Tusi Shamakhy Astrophysical Observatory of the National Academy of Sciences of Azerbaijan using an echelle spectrometer. The following features have been revealed for the first time: the moving discrete absorption components in the core of the H line from the red side to the violet, the stable emission in the violet wing of the H line, the antiphase variation of the radial velocities and equivalent widths of the H line, and the independence of the changes of the equivalent widths of the H line from the phase of the orbital period. No spectral features according to which this star could be considered as a source of X-ray radiation have been found.
