Electromagnetic Radiation and Motion of Dust Particle - A Simple Model

TL;DR

This paper presents an analytical model for dust particle motion influenced by solar electromagnetic radiation, highlighting how initial conditions affect long-term orbital evolution and potential deviations from traditional models.

Contribution

It introduces a simple, exact analytical model considering mirror-like dust particles, emphasizing the importance of initial conditions in orbital evolution.

Findings

Particles may spiral outward due to electromagnetic forces.

Long-term trajectories depend heavily on initial conditions.

Real dust particle motion can differ from standard assumptions.

Abstract

A simple model for motion of dust particle (meteoroid) under the action of (solar) electromagnetic radiation is presented. The particle of the form of plane mirror is taken into account and exact analytical results are presented. As for long-term orbital evolution, particle may spiral outwards the central body (Sun); initial conditions are important. As a consequence, motion of real dust particles may differ from that generally considered.
