Scientific paper

Using absolute spectrophotometrical data on the binary stars β Lyr and ν Sgr the variability of depression at λ5200 dependent on the phase of the orbital cycle has been studied. The variations of the equivalent width of the depression in the spectrum of β Lyr correlate with the magnetic field variations. The magnetic field strength of ν Sgr is predicted to be ⪆4 kGauss.
