Abstract

A theoretical description of a possible mechanism to excite Langmuir turbulence in the upstream region of the earth's bow shock is proposed. The mechanism relies on the spatial inhomogeneity of energetic electron streams accelerated at the shock foot and propagating upstream along the magnetic field. The estimation of growth rates and wave amplitudes is in reasonable agreement with the observations. These features have been observed by the AMPTE (Active Magnetospheric Particle Tracer Explorer) spacecraft in the upstream region when the particles are connected by the magnetic field to the shock.
