Planetary Science Seminar spring-2021

I will discuss how the history of core convection in rocky planets is reflected in their magnetic fields, from Earth to Mars and (potentially) rocky exoplanets. I will also discuss how magnetic field intensities are expected to be limited by the thermal and electrical conductivities of the lower mantle and core, how magnetic fields can limit atmospheric escape, and the prospects for detecting exoplanet magnetic fields by radio cyclotron emission.
