Nonlinear Processes in Collisionless Space Plasmas: Bridging Theory, Modeling, and Observations
Session ID#: 247425
Session Description:
Nonlinear processes in collisionless space plasmas span a wide range of temporal and spatial scales, playing critical roles including: 1) transferring free energy from ring current particles to drive electromagnetic waves; 2) rapidly accelerating charged particles in planetary magnetospheres and the solar wind; 3) enabling efficient radial transport of energetic particles; 4) driving pitch-angle scattering and precipitation of particles into planetary atmospheres. This session invites contributions that explore these phenomena through theoretical, modeling, and observational approaches. We particularly welcome studies integrating insights across different plasma environments, including Earth’s magnetosphere (e.g., Arase, MMS, THEMIS), Jupiter’s magnetosphere (e.g., JUNO), and the solar wind (e.g., Parker Solar Probe).We also encourage submissions leveraging data from CubeSats and balloon missions, especially those focused on electron precipitation and its connection to nonlinear processes. By fostering dialogue across disciplines and datasets, this session aims to advance our understanding of the fundamental physics governing space plasmas.
