Spectral investigation of eclipsing binary stars at the stage of mass exchange
Description
From spectrograms with dispersion 9-37 A/mm the spectral characteristics of eight eclipsing binary stars were studied showing the effects of mass exchange. Spectral types of stars were determined as were temperatures of excitation, parameters of damping, turbulent velocities, electron number densities, chemical composition of stellar atmospheres and displacements of lines in radiation and absorption, variations in characteristics of lines, as a function of phase. It is shown that appreciable deviations of physical conditions from normal ones were not observed. Schemes-models of studied stellar systems are presented and discussed.
