Collisions that induce melting and vaporization can have a substantial effect on the thermal and geochemical evolution of planets. However, the thermodynamics of major minerals are not well known at the extreme conditions attained during planet formation. We obtained new data at the Sandia Z Machine and use published thermodynamic data for the major mineral forsterite (Mg 2 SiO 4 ) to calculate the specific entropy in the liquid region of the principal Hugoniot. We use our calculated specific…

TLDR
The results provide experimental support to the idea that giant impacts can transform much of the mantles of rocky planets into supercritical fluids.
Liquid‐Vapor Coexistence and Critical Point of Mg2SiO4 From Ab Initio Simulations
Hypervelocity impact‐driven vaporization is characteristic of late‐stage planet formation. Yet the behavior and properties of liquid‐vapor mixtures of planetary materials of interest are typically
Dependencies of Mantle Shock Heating in Pairwise Accretion
The final assembly of planets involves mutual collisions of large similar-sized protoplanets (“giant impacts”), setting the stage for modern geologic and atmospheric processes. However, thermodynamic

The Principal Hugoniot of Iron‐Bearing Olivine to 1465 GPa
Shock compression experiments on natural compositions are imperative to accurately model planetary accretion and the interior dynamics of planets. Combining shock compression experiments from the
Chondrules from high-velocity collisions: thermal histories and the agglomeration problem
We assess whether chondrules, once-molten mm-sized spheres filling the oldest meteorites, could have formed from super-km/s collisions between planetesimals in the solar nebula. High-velocity
Shock-compressed silicon: Hugoniot and sound speed up to 2100 GPa
The behavior of silicon (Si) above millions of atmospheres >100 GPa is important to understand the structure and evolution of terrestrial planets,1–4 as well as the performance of inertial

We use first principles molecular dynamics simulations coupled to the thermodynamic integration method to study the hcp-bcc transition and melting of beryllium up to a pressure of 1600 GPa. We derive
Shock experiments on basalt—Ferric sulfate mixes and their possible relevance to the sulfide bleb clusters in large impact melts in shergottites
Large impact‐melt pockets in shergottites contain both Martian regolith components and sulfide/sulfite bleb clusters that yield high sulfur concentrations locally compared to bulk shergottites. The
