Physicists at Lawrence Livermore National Laboratory and the University of Illinois at Urbana-Champaign have done First-Principles Molecular Dynamics (FPMD) simulations on LLNL’s high performance computing systems to “determine the equation of state of the hydrogen-helium system at extremely high temperatures (4,000-10,000 degrees Kelvin), similar to what would be found in the interior of Saturn and Jupiter.” Read more here.
