Emission of Oblique Propagating Electromagnetic Ion Cyclotron Waves through Hot Injection of Ion Beams for Ring Distribution with A.C. Electric Field in the Jovian Magnetosphere

Abstract

The Ulysses spacecraft's detection of electromagnetic ion-cyclotron waves in the Jovian magnetosphere is examined in this research. In this area, several kinds of high-frequency radio emissions from resonant interactions have been detected. In light of the parallel propagation of electromagnetic ion-cyclotron waves, the study focuses on the wave-particle interactions between these waves and fully ionized magnetospheric plasma particles. As a result, the dispersion relation with a ring distribution in a collisionless magneto-plasma at 17 RJ with a parallel alternating current (AC) electric field may be thoroughly examined. We derive a relativistic growth rate expression using a kinetic approach and a method of characteristics. We also examine injection events captured in the Jovian magnetosphere by the Galileo spacecraft's energetic particle detector (EPD). We perform a parametric analysis of different plasma properties, including temperature anisotropy, AC frequency, and relativistic variables, after a hot ion beam is injected to investigate their impact on the growth rate, which is displayed.
