From Early Earth to Hot Rocky Exoplanets

Rapid advances in exoplanet research and planetary exploration are blurring the traditional boundaries between earth sciences, geology, planetary science, and astronomy. While a planet's interior remains difficult to access, it plays a fundamental role in shaping surface conditions. For example, on Earth, plate tectonics and the presence of a magnetic field are direct manifestations of internal dynamics. The interior of the Earth, the planet we understand best, has been extensively studied over the past century using seismic imaging, geochemistry, petrology, and geodynamic modeling. These studies have uncovered major processes that have shaped and continue to shape our planet. The question now is : Do these processes also apply to other rocky planets? How can we extend our knowledge of Earth to planets within our solar system and beyond? And can studying other planets help us learn more about Earth itself? In this presentation, I will provide a specific example of how studying the Early Earth can help us understand a particular class of rocky exoplanets known as lava worlds.
