On Jovian magnetospheric natural instability

Abstract

In this paper an attempt has been made to study the natural instability of Jovian magnetosphere from an analysis of the electron and whistler wave interactions. It is observed that for the wave frequency of 3-300 kHz, the resonant energies fall in the range 5-50 MeV where extensive electron flux measurements have been carried out by Pioneers 10 and 11, and Voyager 1. Further, the results clearly indicate how the features in the whistler wave spectrum selectively interact with well-defined subsets of the trapped energetic electron population.
