Cosmic ray acceleration in sources by supersonic turbulence.
Abstract
A study is presented of the acceleration of fast particles by arbitrary large-scale motions of plasma with stochastically distributed shock fronts. The possibility that supersonic turbulence can develop in nonstationary astrophysical objects is examined. Observational data and theoretical considerations are presented which support the acceleration of cosmic rays by supersonic turbulence in the interplanetary medium, in the vicinity of O and B type supergiants, in supernova remnants, in the interstellar medium, and in the intergalactic medium.
