摘要：
We estimate the time scale due to damping mechanism responsible for the rocket effect. We consider a two-fluid model in which both components can oscillate, and we consider two different kinds of r-mode oscillations, one predominantly associated with comoving displacements of the two fluids and the second associated with countermoving out-of-phase, displacements. In the former case, we find that the dissipation mechanism associated with the rocket effect is not able to prevent the growth of r-mode instability. In the latter case, the rocket effect prevents the growth of r-mode instability for temperatures larger than about 10(9) K.
