Using ab initio molecular dynamics simulations, we recently calculated equation of states for five main constituents of planetary interiors: H, He, H2O, SiO2 and Fe. These equations of states are multi-‐phases, include liquid and solid phases, and aim at building planetary and exoplanetary interior models solely based on ab initio predictions. This talk will concentrate on the results obtained for silica and iron where we used ab initio predictions, laser shock experiments combined with XANES (X-ray near edge spectroscopy) measurements to study the physical properties of these constituents at planetary core conditions.
