The discovery of the donor magnetic field has repeatedly posed the task of a thorough study of the phenomenon , which is based on the concept of the influence of the magnetic field on the processes of the formation of gaseous structures and mass transfer in the Beta Lyrae system . This article provides an overview , analysis , and synthesis of the results of a variety of long-term observations as a necessary basis for further clarification of issues aimed primarily at the study of magnetized gaseous structures . As a part of such a study , it was found that the structure of the gaseous flows between the donor and the gainer varies in some way depending on the phases of the orbital period ; and , accordingly , that the donor magnetic field influences the formation of these moving magnetized structures . The analysis of the masses of both components for use in further scientific works suggests that the following values are optimal : 2.9 M _ { \odot } for the donor and 13 M _ { \odot } for the gainer . The study of satellite lines as a certain phenomenon leads to the fact that the accretion disk surrounding the gainer consists of two parts : the external satellite disk and the internal massive opaque disk . From the analysis of all observations and studies of the magnetic field , observations on the 6-m telescope can be considered the most reliable . They have formed the spatial configuration of the donor magnetic field , which is important for studying and understanding the features of the mass transfer in this interacting system . Further evidence regarding the picture of the magnetized accretion structures as the special phenomenon will be presented in the following articles .
