Propagation of EMIC Waves using Kappa Distribution in the Jupiter’s Magnetosphere

The propagation of Electromagnetic Ion-Cyclotron (EMIC) Waves is observed in Jupiter’s Magnetosphere with varying anisotropy temperature. Voyager∼2 by NASA showed Jupiter’s plasma Magnetosphere contained humungous high energy particles in its tail. Thus, by using Kinetic Theory approach for the systems of Jovian type, the growth rate for EMIC waves is iterated and with the help of method of characteristic solution, the dispersion relation is computed. Due to above mentioned constraint, we apply Kappa distribution rather than Maxwellian distribution. These computations are solely focused on the parallel propagation as well as on the oblique propagation of EMIC waves considering variation in temperature anisotropy, ions energy density and propagation angle with respect to the direction of magnetic field. For Jupiter’s magnetosphere, it is found that the above parameters support the growth rate of EMIC waves. It is also observed from the plotted graphs that EMIC waves for oblique propagation have significantly grown more than that for parallel propagation. And more the energy of ions, more the growth is observed. Results obtained after computations are appropriate for the applications in the environment pertaining to space plasma and magnetosphere for the planetary comparative study of the solar system.
