Planetary core dynamics and the geodynamo
Co-organized by PS1
Convener: Jerome Noir | Co-conveners: Daria Holdenried-Chernoff, Maylis Landeau, Santiago Andres Triana

Since W. Hopkins first suggested in the mid-nineteenth century that a planet’s interior could be studied through the variations of its rotation, and J. Larmor’s early twentieth-century idea that planetary magnetic fields originate from dynamo action in a fluid conductive layer, the dynamics of planetary cores have garnered increasing attention. These dynamics are now recognized as fundamental components of planetary evolution models, contributing to heat and angular momentum balance, energy dissipation, and the generation of magnetic fields, which can be observed both in situ and remotely.

The growing volume of data from satellite and Earth-based missions necessitates ongoing efforts to enhance our understanding of these dynamics through theoretical, numerical, and experimental research. In this session, we welcome contributions from all disciplines to provide a comprehensive overview of the current state of planetary core and geodynamo models. This includes research on thermal and compositional convection, mechanically driven flows by precession/nutation, libration, and tides, as well as dynamo processes.
