Scientific paper

Some results are analysed of a previous spectroscopic investigation of the supergiant HDE 226868 (based on six-year observations at the 6 m telescope) with the purpose of searching for possible variations in the spectrum connected with the precession of the rotation axis of the star's upper layers. It is noted that the spectral type and the He I λ4471 line halfwidth show a coordinated behaviour with the phase of the 39-day period in the frame of the precession hypothesis.
