摘要：

We have performed Monte Carlo simulations of the rotation of single stars and companions of compact objects (The compact objects are white dwarfs (WDs) and neutron stars (NSs)) in close binaries. We present a comparison between the rotation of companions of compact objects and that of single stars. We find that the rotation of the companions of compact objects is on average faster than that of the single stars. According to the distribution of the orbital period and the rotation angular velocity, we find that the rotation of the companions of compact objects is mostly accelerated by stable mass transfer. Tidal forces of the compact object can also affect the rotation of companion.
