Scientific paper

The absorption spectrum of the interacting binary RY Sct is investigated on the basis of high-dispersion spectrograms. Wide, shallow Si III, H, He I, and other lines reflecting the orbital motion of the faint secondary component are identified. The half-amplitude of the radial velocity curve of these lines is close to 70 km/s. Elements of the RY Sct orbit are calculated. The mass ratio is 3.32, the mass of the bright B0 component is 8 solar masses, and that of the secondary B2 component is 26 solar masses. Features of the manifestation of developed circumstellar gaseous structures in the spectrum of RY Sct are examined.
