Generation of VLF hiss and chorus in Jupiter’s magnetosphere

Abstract

Using the plasma and field parameters corresponding to <i>L</i>=8, temporal growth rates of VLF waves have been computed for a non-Maxwellian electron distribution leads the generation of VLF chorus just below the one-half of the electron gyrofrequency and the presence of nonthermal drifted Maxwellian tail leads the instability below one-fourth of the electron gyrofrequency. The computed results are in good agreement with those reported by the Voyager 1 and 2 plasma wave experiments.
