Modeling the Dynamics of Dust Particles in the Gravitational and Electrostatic Fields of a Primitive Asteroid Taking into Account the Sublimation of Water Ice

This article presents a model of the dynamics of dust particles near a primitive (with low-temperature mineralogy including water ice) asteroid. Taking into account the small size and mass of dust particles, their motion is determined by disturbing factors such as solar radiation pressure and the electrostatic field resulting from the interaction of the solar wind with the asteroid surface. The Particle-in-Cell method is used to calculate electrostatic forces, which allows us to significantly simplify the modeling of the interaction of solar wind plasma with the asteroid surface.
