Incompatibility of iron in post-perovskite and the stability of basal magma oceans in super-Earths

Francis Dragulet, Lars Stixrude

Post-perovskite is expected to dominate much of the solid mantles of rocky exoplanets, yet iron partitioning between post-perovskite and silicate melt, which controls the compositi…

An Equation of State for Supercritical Silicate-Hydrogen Mixtures at Sub-Neptune Interior Conditions

Sarah P. Marcum, Lars Stixrude, Edward D. Young

Many sub-Neptunes are expected to contain long-lived molten silicate interiors beneath dense H2-rich envelopes. At pressures and temperatures near the atmosphere-interior boundary,…

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…

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…

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…

MgO Miscibility in Liquid Iron

Leslie Insixiengmay, Lars Stixrude

We explore phase equilbria on the MgO-Fe join as a prototype of lithophile-core interaction in terrestrial planets. Our simulations, based on density functional theory, are based o…

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…

The miscibility of hydrogen and water in planetary atmospheres and interiors

Akash Gupta, Lars Stixrude, Hilke E. Schlichting

Many planets in the solar system and across the galaxy have hydrogen-rich atmospheres overlying more heavy element-rich interiors with which they interact for billions of years. At…
