Planetary cores host a rich variety of dynamical processes related to the thermal, compositional, and magnetic evolution of Earth and other planetary bodies. Understanding core dynamics and the magnetic field generation process is key to constraining the evolution of planetary interiors. Coupling between planetary cores and surrounding solid layers can influence these dynamics, providing further constraints on planetary evolution.

Magnetic field generation in planetary cores results from flows of electrically conducting, iron-rich liquids strongly influenced by rotation and driven by a combination of thermal convection, compositional convection, and mechanical forcing. Observations of the geomagnetic field and other planetary magnetic fields represent unique windows into these flows. Numerical models and experiments can be used to understand these observations and provide constraints on dynamical regimes of planetary cores and their coupling with surrounding solid layers.

In this session, we welcome observational, theoretical, numerical, and experimental studies aimed at improving our understanding of the complex dynamics occurring in planetary cores and of the evolution of planetary magnetic fields. These include research on thermal, compositional, and mechanically forced convection in planetary cores, magnetic field generation and observation, and dynamical coupling between solid layers and planetary cores.
