title: Metal-Silicate equilibrium in the magma ocean
abstract: The formation of the core transforms gravitational energy into heat and the distribution of the energy within the Earth is still debated and depends on the core formation process considered.
Iron rain in the surface magma ocean is supposed to be the first mechanism of separation for Earth-like planets.
In the presentation, we treat the metal-silicate separation process in the magma ocean by numerical simulation and clarify the evolution of the thermal and chemical structure.
