The hydrogen-helium EOS at high pressures: Planetary interiors

The high-pressure equation of state for hydrogen and helium is needed to model giant planets such as Jupiter or Jupiter-like extrasolar planets. Under those conditions, pressure dissociation and ionization processes occur which lead simultaneously to a transiton from a nonconducting to a metallic state. New theoretical results for the equation of state and the transport properties of hydrogen, helium, and their mixtures are compared with shock-wave experiments, and models for planetary interiors are presented.
