摘要：
A new mechanism for the generation of X-ray luminosity in binary Be/X-stars is proposed. Using the model of the expanding envelope of optical component of binary Be/X-star it was shown that the rate of mass transfer through the vicinity of L-1 is sufficient to generate the observed X-ray luminosity of Be/X-stars. The relationship between the orbital period of the system and the magnitude of X-ray flux was discovered. The relationship between the orbital period of the system and the mass transfer rate, obtained from the simulation results, corresponds to the observed dependence of the maximum X-ray flux during the outburst on the orbital period for binary Be/X stars.
