Abstract

Generating Magnetic Fields in Earth, Venus, and Super-Earth Exoplanets

Earth's global magnetic field has survived for at least 3.5 billion years, yet Venus lacks a dynamo today. I will explore possible explanations for this dichotomy and discuss related implications for the internal structure and evolution of massive, rocky exoplanets.
