Excitation of wakefield around pulsars
  We study the generation of the wakefields by means of the high energy radiation of pulsars. The problem is considered in the framework of a one dimensional approach. We linearize the set of governing equations consisting of the momentum equation, continuity equation an Poisson equation and show that a wavelike structure will inevitably arise relatively close to the pulsar.
