Effect of temperature anisotropy on Alfven waves in multicomponent magnetospheric plasma

The main objective of the present investigation is to examine the effect of temperature anisotropy on Alfven waves in multi-component plasma by using the method of kinetic approach and using different plasma parameters in auroral acceleration region. In this paper, we are considering the multi-component (Ions and electrons) plasma for the calculations of dispersion relation, growth/damping rate and growth length on Alfven waves. Dispersion relation, growth/damping rate and growth length of Alfven waves are measured in multi-component plasma consisting of mixture of Hydrogen (H+), Helium (He+) and Oxygen (O+) ions. An Alfven waves is an important electromagnetic wave that transports electromagnetic energy in many space and astrophysical regions. These waves parallel propagate along the magnetic field with parallel wave vector in the x-z plane. Curves show that the damping rate increases of waves with increases temperature anisotropy.
