Aims. The secondary atmospheres of terrestrial planets form and evolve as a consequence of interaction with the interior over geological time. We aim to quantify the influence of planetary bulk composition on the interior–atmosphere evolution for Earth-sized terrestrial planets to aid in the interpretation of future observations of terrestrial exoplanet atmospheres. Methods. We used a geochemical model to determine the major-element composition of planetary interiors (MgO, FeO, and SiO2… 

Mantle Degassing Lifetimes through Galactic Time and the Maximum Age Stagnant-lid Rocky Exoplanets Can Support Temperate Climates

The ideal exoplanets to search for life are those within a star’s habitable zone. However, even within the habitable zone, planets can still develop uninhabitable climate states. Sustaining a

Blue Marble, Stagnant Lid: Could Dynamic Topography Avert a Waterworld?

Topography on a wet rocky exoplanet could raise land above its sea level. Although land elevation is the product of many complex processes, the large-scale topographic features on any geodynamically

The Diversity of Exoplanets: From Interior Dynamics to Surface Expressions

The coupled interior–atmosphere system of terrestrial exoplanets remains poorly understood. Exoplanets show a wide variety of sizes, densities, surface temperatures, and interior structures, with

Growth and Evolution of Secondary Volcanic Atmospheres: II. The Importance of Kinetics

Volcanism is a major and long-term source of volatile elements such as C and H to Earth’s atmosphere, likely has been to Venus’s atmosphere, and may be for exoplanets. Models simulating volcanic

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 case of how

Vertically resolved magma ocean–protoatmosphere evolution: H 2 , H 2 O, CO 2 , CH 4 , CO, O 2 , and N 2 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 distribution of the

Geoastronomy: Rocky planets as the Lavosier-Lomonosov Bridge from the non-living to the living world

WEB SUMMARY Life on Earth emerged at the interface of the planet’s geosphere, hydrosphere and atmosphere. This setting serves as our basis for how biological systems originate on rocky planets. Often

Oxygen controls on magmatism in rocky exoplanets

Experimental evidence is provided for a significant effect of planetary oxygen abundance on melting of rocks, showing that higher rock oxygen abundance leads to easier rock melting, implying that refractory oxygen abundance can directly control exoplanetary differentiation dynamics by affecting the conditions under which magmatism occurs, even in the absence of iron or volatiles.

Hidden Water in Magma Ocean Exoplanets

We demonstrate that the deep volatile storage capacity of magma oceans has significant implications for the bulk composition, interior, and climate state inferred from exoplanet mass and radius data.

Experimental Determination of Mantle Solidi and Melt Compositions for Two Likely Rocky Exoplanet Compositions

For rocky exoplanets, knowledge of their geologic characteristics such as composition and mineralogy, surface recycling mechanisms, and volcanic behavior are key to determining their suitability to



The core-mantle boundary region

The 75 year history of the American Geophysical Union has accompanied great advances in our understanding of the physics and chemistry of the transition zone between the Earth's core and mantle. The

Ferrous iron partitioning between magnesium silicate perovskite and ferropericlase and the composition of perovskite in the Earth's lower mantle

[1] We have investigated the exchange of Fe and Mg between magnesium silicate perovskite (Mg-Pv) and ferropericlase (Fp) at 25 GPa and 2400 to 2600 K using a Kawai-type multianvil apparatus. Each

One‐Dimensional Convective Thermal Evolution Calculation Using a Modified Mixing Length Theory: Application to Saturnian Icy Satellites

Solid‐state thermal convection plays a major role in the thermal evolution of solid planetary bodies. Solving the equation system for thermal evolution considering convection requires 2‐D or 3‐D

Hydrogen partition coefficients between nominally anhydrous minerals and basaltic melts

We have measured hydrogen partition coefficients between nominally anhydrous minerals (olivine, pyroxenes) and basaltic melts in 13 hydrous melting experiments performed at upper mantle P‐T

Unified analyses for P-V-T equation of state of MgO: A solution for pressure-scale problems in high P-T experiments

[1] In order to determine an accurate and reliable high-pressure and high-temperature equation of state (EOS) of MgO, unified analyses were carried out for various pressure-scale-free experimental

Inward migration of the TRAPPIST-1 planets as inferred from their water-rich compositions

Multiple planet systems provide an ideal laboratory for probing exoplanet composition, formation history and potential habitability. For the TRAPPIST-1 planets, the planetary radii are well

Ranges of Atmospheric Mass and Composition of Super-Earth Exoplanets

Terrestrial-like exoplanets may obtain atmospheres from three primary sources: capture of nebular gases, degassing during accretion, and degassing from subsequent tectonic activity. Here we model
