Detailed description

This project investigates the effect of the exospheric sodium ion population on the growth of Kelvin-Helmholtz waves in the velocity shear layer at Mercury's magnetotail. We use a 2D hybrid simulation which treats ions as individual macroparticles and electrons as a massless, charge-neutralizing fluid. This enables us to study the kinetic processes associated with the interactions between solar wind proton, magnetospheric proton, and magnetospheric sodium ion populations to reproduce the apparent sodium scale vortices observed by MESSENGER at Mercury.
