In this paper, firehose instability has been generated by injection of hot electron beam in the magnetosphere of Jupiter for loss-cone generalized distribution using kinetic approach. The effect of temperature anisotropy and ratio of number density of hot and cold electrons has been studied. In the generalized distribution, loss-cone distribution index j = 0 (Bi-Maxwellian) is considered as a cold background and j = 1 (loss-cone) is for hot electron injection. After using computer technique, growth rate for firehose instability has been calculated in the Jupiter magnetosphere at Rj = 17.

摘要

In this paper, firehose instability has been generated by injection of hot electron beam in the magnetosphere of Jupiter for loss-cone generalized distribution using kinetic approach. The effect of temperature anisotropy and ratio of number density of hot and cold electrons has been studied. In the generalized distribution, loss-cone distribution index j = 0 (Bi-Maxwellian) is considered as a cold background and j = 1 (loss-cone) is for hot electron injection. After using computer technique, growth rate for firehose instability has been calculated in the Jupiter magnetosphere at Rj = 17.
