Energetic charged particles are ubiquitous in the universe, and magnetized objects (planets, moons and some stars) are ideal laboratories for studying dynamics under relatively stable conditions. These energetic particles interact with a wealth of plasma waves that can have a broad range of impacts on the particle populations, leading to complex and diverse dynamics. Each system weighs these processes differently, enabling us to disentangle their effects while aiming to develop a universal understanding of space physics. Such comparisons are timely because recent spacecraft missions provide a wealth of measurements at Earth, Jupiter, Saturn, and their moons, and exploration of Uranus and Neptune is expected in the near future. This session invites presentations based on theory, simulations, or observations focusing on energetic charged particles, their fundamental processes in the radiation belts (including wave-particle and radial diffusion) and as part of magnetosphere-ionosphere coupling, moon surface weathering, or other relevant magnetospheric system interaction.
