Pressure-induced desalting of NaCl-bearing ice VII: A compositional filter in water-rich planets

Alasdair Nicholls, Tomasz Poreba, Xi Zhu +6

Sodium chloride is a major component of extraterrestrial oceans, but it is generally assumed to be excluded from the high-pressure ice mantles of water-rich planets. Here we show t…

Impact-induced Vaporization During Accretion of Planetary Bodies

Adrien Saurety, Razvan Caracas, Sean N. Raymond

Giant impacts dominate the late stages of accretion of rocky planets. They contribute to the heating, melting, and sometimes vaporizing of the bodies involved in the impacts. Due t…

Analyzing melts and fluids from ab initio molecular dynamics simulations with the UMD package

Razvan Caracas, Anais Kobsch, Natalia V. Solomatova +3

We develop a Python-based open-source package to analyze the results stemming from ab initio molecular-dynamics simulations of fluids. The package is best suited for applications o…

The Shock Physics of Giant Impacts: Key Requirements for the Equations of State

Sarah T. Stewart, Erik J. Davies, Megan S. Duncan +6

We discuss major challenges in modeling giant impacts between planetary bodies, focusing on the equations of state (EOS). During the giant impact stage of planet formation, rocky p…

Reconciling Magma-Ocean Crystallization Models with the present-day Structure of the Earth's mantle

Maxim D. Ballmer, Diogo L. Lourenço, Kei Hirose +2

Terrestrial planets are thought to experience episode(s) of large-scale melting early in their history. Fractionation during magma-ocean freezing leads to unstable stratification w…

Prediction of polar ordered oxynitride perovskites

Razvan Caracas, R. E. Cohen

Using a materials by design approach, the authors find a class of ordered oxynitride piezoelectrics with perovskite structure. They predict that ordered YSiO2N and YGeO2N are chara…

Theoretical determination of the Raman spectra of MgSiO3 perovskite and post-perovskite at high pressure

Razvan Caracas, Ronald E. Cohen

We use the density functional perturbation theory to determine for the first time the pressure evolution of the Raman intensities for a mineral, the two high-pressure structures of…
