Initial Thermal States of Super‐Earth Exoplanets and Implications for Early Dynamos

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 2, February 2025.
Abstract The accretion of Earth and the formation of a metallic core released a large amount of primordial heat and may have enabled its evolution into a habitable world. Metal‐silicate segregation likely occurs in super‐Earth exoplanets as well, but its influence on their initial thermal states has not been fully examined.

Magma Ocean Evolution at Arbitrary Redox State

open access: yesJournal of Geophysical Research: Planets, Volume 129, Issue 12, December 2024.
Abstract Interactions between magma oceans and overlying atmospheres on young rocky planets leads to an evolving feedback of outgassing, greenhouse forcing, and mantle melt fraction. Previous studies have predominantly focused on the solidification of oxidized Earth‐similar planets, but the diversity in mean density and irradiation observed in the low ...
