Abstract

A new mechanism is proposed for the explanation of synchronous rotations in AM Herculis-type binaries. In contrast to the resistive mechanism of Josset al. (1979), our model predicts that an asynchronous rotation, if it is present, damps exponentially and the damping time is inversely proportional to the electrical conductivity. It is shown by using the parameters which fit for AM Herculis that a typical damping time is very short compared with the lifetime of the system.
