AbstractThis paper addresses particle simulation analysis on electric environment around lunar vertical holes and their associated subsurface caverns. The analysis is based on the kinetic (particle-in-cell) descriptions of solar wind plasma dynamics, lunar surface charging, and near-surface plasma sheath formation. The obtained electrostatic environment around the distinctive landscape is provided for numerical model predictions of dynamics and charging processes of micron/submicron-sized dust grains. The paper mainly reports the following two results: 1. enhanced potential deviation between sunlit lunar surfaces inside and outside the holes, detected when assuming the presence of a subsurface cavern, and 2. continual transport of dust grains sustained by their stochastic charge attainment/lost from surrounding plasma.
