Ab Initio Entropy Calculations of Water Predict the Interiors of Uranus and Neptune to Be 15%–30% Colder than Previous Models

The Astrophysical Journal
Ab initio free energy calculations are employed to derive the entropy of liquid and superionic water over a wide range of conditions in the interiors of Uranus and Neptune.

The Linear Mixing Approximation in Silica–Water Mixtures at Planetary Conditions

The Astrophysical Journal
The linear mixing approximation (LMA) is often used in planetary models for calculating the equations of state (EOS) of mixtures. A commonly assumed planetary composition is a mixture of rock and water. Here we assess the accuracy of the LMA for pressure–

Variations in the Radius Distribution of Single- and Compact Multiple-transiting Planets

The Astronomical Journal
Previous work has established the enhanced occurrence of compact systems of multiple small exoplanets around metal-poor stars. Understanding the origin of this effect in the planet formation process is a topic of ongoing research.

Using Array Seismology to Study Planetary Interiors [PDF]

, 2011
: Stratification is a dominant feature of all planetary interiors. Fine-scale structure associated with layering, as well as heterogeneities hold important clues on a planet's compositional, thermal, and dynamical state, as well as its evolution.

Accelerating the Discovery of Steady‐States of Planetary Interior Dynamics With Machine Learning

Journal of Geophysical Research: Machine Learning and Computation
Simulating mantle convection often requires reaching a computationally expensive steady‐state, crucial for deriving scaling laws for thermal and dynamical flow properties and benchmarking numerical solutions.
