Shock-Compressed Methane to 400 GPa

ORAL

Abstract

Methane plays an important role in planetary physics and is a major constituent of giant planet atmospheres. Methane is predicted to have an intricate phase diagram at high pressures, including the conditions inside planet interiors.[1][2][3] We present shock-compression data to 400 GPa for methane. The methane samples were precompressed in a diamond-anvil cell to a range of densities in order to access a broad range of extreme conditions. This material is based upon work supported by the Department of Energy National Nuclear Security Administration under Award Number DE-NA0003856.
