[PPS13-12] Particle simulations on charged dust dynamics in the lunar plasma environment
Keywords:the Moon, dust grains, plasma, lunar surface charging, vertical hole, PIC simulation
In the present study, we apply our original particle-in-cell simulator EMSES, which have been used to study spacecraft-plasma interactions, to prediction of charged dust dynamics in the day-side lunar plasma environment. For this, we reproduce the near-surface electrostatic environment and develop a numerical model of dust charging in it by conducting the plasma particle simulations. We also consider an effect of characteristic lunar surface topography such as the lunar vertical holes, which are recently discovered by the Kaguya satellite. We will show preliminary simulation results on the charged dust environment near the moon surface.
