Scientific paper

The present paper is concerned with a careful analysis of the absorption spectrum of the eclipsing binary CQ Cep. It had been found that practically all the emission lines in the spectra of this binary are strongly distorted by absorption features. The present study is based on observational material obtaiend with the aid of camera II of the OZSP spectrograph on the BTA 6-m telescope. The observations were made in August and October 1981 and August 1982. It is pointed out that the recordings are characterized be high dispersion and high resolution. On the basis of a detailed investigation, it was concluded that three systems of absorption lines exist in the spectrum. The absorption lines belonging to the o satellite could be isolated. Attention is given to the radial-velocity curves of the O satellite and the WR component, the results of the solution of the radial-velocity curves, the spectral classification of the satellite, and the masses and sizes of the orbits of the components of CQ Cep.
