Plausible constraints on the range of bulk terrestrial exoplanet compositions in the solar neighborhood
Rocky planet compositions regulate planetary evolution by affecting core sizes, mantle
properties, and melting behaviors. Yet, quantitative treatments of this aspect of exoplanet …

Vertically Resolved Magma Ocean–Protoatmosphere Evolution: H2, H2O, CO2, CH4, CO, O2, and N2 as Primary Absorbers
The earliest atmospheres of rocky planets originate from extensive volatile release during
magma ocean epochs that occur during assembly of the planet. These establish the initial …

The nominal ranges of rocky planet masses, radii, surface gravities, and bulk densities
CT Unterborn, SJ Desch, J Haldemann… - The Astrophysical …, 2023 - iopscience.iop.org
The two primary observable quantities of an exoplanet—its mass and radius—alone are not
sufficient to probe a rocky exoplanet's interior composition and mineralogy. To overcome …

Growth and evolution of secondary volcanic atmospheres: I. Identifying the geological character of hot rocky planets
The geology of Earth and super‐Earth sized planets will, in many cases, only be observable
via their atmospheres. Here, we investigate secondary volcanic atmospheres as a key base …

A mineralogical reason why all exoplanets cannot be equally oxidizing
From core to atmosphere, the oxidation states of elements in a planet shape its character.
Oxygen fugacity () is one parameter indicating these likely oxidation states. The ongoing …
