我们考虑由于与另一个物体的近距离接触而引起的均匀旋转的全对流物体的惯性模式的激发。这可能导致潮汐捕获或轨道圆化，具体取决于初始轨道是不受束缚还是高度偏心。我们为响应问题开发了一种通用的自伴形式，并考虑到 n= 1.5 的全多变体的 m= 2 的惯性模式来解决该问题。因此，我们能够在这种情况下证明，惯性模态的激发主导了大冲击参数的响应，因此在潮汐能和角动量交换或大偏心率引起的轨道圆化的计算中不能忽略。
We consider the excitation of the inertial modes of a uniformly rotating fully convective body due to a close encounter with another object. This could lead to a tidal capture or orbital circularization depending on whether the initial orbit is unbound or highly eccentric. We develop a general self-adjoint formalism for the response problem and thus solve it taking into account the inertial modes with m= 2 for a full polytrope with n= 1.5. We are accordingly able to show in this case that the excitation of inertial modes dominates the response for large impact parameters and thus cannot be neglected in calculations of tidal energy and angular momentum exchange or orbital circularization from large eccentricity.
