Density functional theory coupled to classical molecular dynamics simulations is used to obtain the equations of state for 29 helium concentrations. The entropy is calculated using a combination of thermodynamic integration of the equation of state and coupling-constant integration. New planetary profiles for Jupiter and Saturn are derived giving strong indications that there is demixing in Saturn but possibly not in Jupiter.
