Polarization Clouds and Dynamical Friction
We argue that dynamical friction can be viewed as the drag exerted on a ‘test’ star by the wake it induces in the field stars. We compute the wakes for the uniform infinite medium and a flat rotating sheet. In the first case we obtain a result which differs by a factor of two from the classical result. In the second case the drag vanishes.
