论文摘要
我们研究二进制系统中质量的交换是一个通道，通过该通道可以通过该通道接收快速旋转。 Hertzsprung-pap中巨大的近距离系统中的质量转移阶段伴随着吸积分的旋转。我们考虑一种质量增加1.5倍的情况。该组件在临界旋转状态下获得质量和角动量。组件的角动量增加了50倍。子午循环在质量转移阶段和质量转移阶段结束后的热时间尺度上有效地将角动量运输到组件内。由于传质，该成分获得了经典为恒星的典型旋转。
We investigate the exchange of mass in a binary system as a channel through which a Be star can receive a rapid rotation. The mass-transfer phase in a massive close binary system in the Hertzsprung-gap is accompanied by the spinning up of the accreting component. We consider a case when the mass of the accreting component increases by 1.5 times. The component acquires mass and angular momentum while in a state of critical rotation. The angular momentum of the component increases by 50 times. Meridional circulation effectively transports angular momentum inside the component during the mass-transfer phase and during the thermal time scale after the end of the mass-transfer phase. As a result of mass transfer, the component acquires the rotation typical of classical Be stars.
