Kinetic Study of Electrostatic Waves in Lunar Wake Plasma with Kappa electrons and Kappa-Beam Electron
Abstract
The electrostatic waves observed in Lunar wake plasma by ARTEMIS satellite are studied in a four-component plasma. The plasma is modelled on par with the satellite observations. The plasma comprises of hot electron & hot electron beam, which follows kappa distribution and protons & doubly charged Helium ions following Maxwell-Boltzmann distribution. Using kinetic theory, the dispersion relation and instability calculation under the suitable expansion of plasma dispersion function is carried out. The effect of various plasma parameters viz. beam velocity, temperature, density is undertaken, and the results will be presented.
