Collisions in the Solar System
Sarah's research focuses on the formation and evolution of planetary bodies. Her primary techniques are shock wave experiments and numerical simulations of planetary collisions. more
Z Experiments Sandia's Z Machine can launch flyer plates up to 40 km/s. Sarah's group is part of a Fundamental Science User Experiment on Z to study shock-induced vaporization of MgO and Fe.
Laser-driven shocks can reach higher pressure-temperature states than gas gun experiments. Using the Janus laser at the LLNL Jupiter Laser Facility, graduate student Rick Kraus and collaborators have studied shock-induced vaporization and the growth of Richtmyer-Meshkov instabilities.
