Название доклада: “Новая модель формирования оболочки в Be-звездах”
Краткое содержание доклада:
The report is devoted to a critical re-examination of the role of the duplicity for the Be phenomenon and for the variability patterns observed for many Be stars. Based on both, dynamical and energy considerations, and a numerical gasdynamical modelling, a new hypothesis of the formation of Be envelopes in binaries, via an outflow from a rapidly rotating B star in a detached binary, is outlined. It is shown that such an outflow is facilitated by the presence of a companion to the B star and leads to the formation of an envelope but not to any significant mass exchange between the binary components.
