Dynamos in planets and stars - similarities and differences

Workshop theme

This one-week workshop will bring together theoreticians, modellers, and observers with interests in planetary and stellar magnetic fields. We invite contributions on all aspects of these fields, from applied mathematicians, stellar, solar and planetary scientists engaged in theory or observations and experts from neighbouring fields.

The latest state of observational evidence for the spatial structure and temporal evolution of magnetic fields of different solar-system planets, possibly of exoplanets, and of different types of stars will be presented. In particular constraints for dynamo theories posed by the new magnetic observations of the Juno and Cassini missions, and the growing data base on the magnetic properties of stars, will be discussed. Similarities and differences between dynamos in planets and stars will be outlined and discussed.

This initial one-week workshop will set the stage for the first theme of the programme and aims to foster in-depth interaction between theorists and modellers on the one side and observers of magnetic fields and other relevant properties of stars and planets on the other.
