The stellar density and Newtonian gravitational potential perturbation induced around a moving massive object. The stellar response includes both a forced component that follows the object and switch-on collective transients. In a homogeneous stable damped model, each late-time spatial harmonic is modified by the gravitational dielectric function at the object's forcing frequency. The wake's force back on the object produces dynamical friction.
