Abstract
We discuss angular momentum transfer by tidally forced oscillations (the dynamical tides) in a massive main-sequence star in a binary system. Because of the periodic gravitational disturbance by the orbital motion of the companion star, low-frequency global oscillations are excited as dynamical tides in the massive main-sequence star. We are mainly interested in the case where the orbital motion of the companion star is in resonance with low-order quadrupole g-modes of the main-sequence star. Dissipation mechanisms associated with nonaxisymmetric oscillations are known to play essential roles in angular momentum transfer in stars
