Metal Saturation and the Redistribution of Hydrogen in Earth's Mantle
Junjie Dong, Lars P Stixrude, Paul D Asimow +1
Iron disproportionation reactions in mantle silicates can produce metallic iron that drives Earth's deep mantle toward metal saturation under reduced conditions. Subducting slabs t…
Differentiation, the exception not the rule -- Evidence for full miscibility in sub-Neptune interiors
Edward D. Young, Aaron Werlen, Sarah P. Marcum +2
We investigate the consequences of non-ideal mixing between silicate, iron metal, and hydrogen for the structures of the cores of sub-Neptunes with implications for super-Earths, w…
Electrical and Thermal Conductivity of Earth's Iron-enriched Basal Magma Ocean
Francis Dragulet, Lars Stixrude
The Earth's earliest magnetic field may have originated in a basal magma ocean, a layer of silicate melt surround the core that could have persisted for billions of years. Recent s…
Phase equilibria of sub-Neptunes and super-Earths
Edward D. Young, Lars Stixrude, James G. Rogers +2
We investigate the consequences of non-ideal chemical interaction between silicate and overlying hydrogen-rich envelopes for rocky planets using basic tenets of phase equilibria. B…
