In this article, the parametric decay and spatial collapse of Langmuir waves driven by an electron beam streaming into the solar wind from the Jovian bow shock was studied.Abstract:
Observations are presented of the parametric decay and spatial collapse of Langmuir waves driven by an electron beam streaming into the solar wind from the Jovian bow shock. Long wavelength Langmuir waves upstream of the bow shock are effectively converted into short wavelength waves no longer in resonance with the beam. The conversion is shown to be the result of a nonlinear interaction involving the beam-driven pump, a sideband emission, and a low level of ion-acoustic turbulence. The beam-driven Langmuir wave emission breaks up into a complex sideband structure with both positive and negative Doppler shifts. In some cases, the sideband emission consists of isolated wave packets with very short duration bursts, which are very intense and are thought to consist of envelope solitons which have collapsed to spatial scales of only a few Debye lengths.read more

Upstream waves and particles: An overview of ISEE results
TL;DR: A brief survey of papers given at the Upstream Wave and Particle Workshop held at the Jet Propulsion Laboratory on April 15-16, 1980 can be found in this article, where the authors view the solar wind-magnetosphere interaction as a general process and state some of the obvious astrophysical implications.

Detailed study of electron plasma waves upstream of the Earth’s bow shock
J. Etcheto,M. Faucheux +1 more
TL;DR: In this paper, a detailed study of electron plasma waves observed upstream of the earth's bow shock and of their relationship to the position of the satellite in the foreshock and to the electron measurements has been carried out.

Electron plasma waves upstream of the Earth's bow shock
TL;DR: In this article, it was shown that this noise, previously understood as narrow band Langmuir waves more or less widened by Doppler shift or nonlinear effects, is in fact composed of two distinct parts: one is a narrow band noise, emitted just above fpe, and observed at the upstream boundary of the electron foreshock.
