[PEM20-09] Upstream wave evolution, particle diffusion and acceleration in the earth's foreshock: One-dimensional PIC simulation
Keywords:earth's foreshock, waves, particle diffusion and acceleration
In this presentation, we discuss how the waves excited by the FAB contribute to the particle diffusion and acceleration in their spatial as well as temporal evolutions. We analyze electromagnetic and electrostatic wave spectra in the foreshock region, and discuss the relation between the evolution of wave spectra and the distribution functions of the solar wind plasma and the FAB. Further we will investigate trajectories of highly accelerated particles and discuss the diffusion and acceleration processes of them.
