Title: Unraveling the interior structure of planets and exoplanets using ab initio equations of states

Abstract: Using ab initio molecular dynamics simulations, we recently calculated the equations of state
for the main constituents of planetary interiors: H, He, H2O, MgSiO3(MgO,SiO2) and Fe.
These equations of states are multi-phases, include liquid and solid phases, and aim at
building benchmark planetary and exoplanetary interior models solely based on ab initio
predictions. This talk will concentrate on Jupiter. We will review how our current
understanding of the behavior of these basic constituents at extreme density temperature
conditions modifies our current understanding of Jupiter interior, not only for the envelop
where metallization of hydrogen and hydrogen-helium demixing is the issue, but also for the
core where the high-pressure melting properties of iron, water, and silicates bring a new
understanding on the nature of giant planet cores.
