The formation and evolution of binary stars are key steps in star formation and evolution, and thus their research has become the core content of modern astronomical research. Although as early as 1976, Bodan Pachenski proposed the theory of the evolution of shared envelopes in binary stars, but it was never confirmed until 2022 when the Yunnan Astronomical Observatory of the Chinese Academy of Sciences and an Australian team first observed the phenomenon of shared envelope ejection in binary stars, which provided support for Bodan Pachenski’s theory, but the true formation mechanism and evolution process of binary stars remain undetermined. For this reason, the author of this paper has proposed a theory of the formation and evolution of binary stars based on the theory of the evolution of common envelopes in binary stars and the theory of tidal disruption events, laying a foundation for establishing a complete theory of star formation and evolution.
Binary star common envelope evolution theory, binary star common envelope ejection phenomenon, tidal disruption, evolution of binary star.
