Chemical Differentiation of Planets: A Core Issue

Hervé Toulhoat, Viacheslav Zgonnik

By plotting empirical chemical element abundances on Earth relative to the Sun and normalized to silicon versus their first ionization potentials, we confirm the existence of a correlation reported earlier. To explain this, we develop a model based on principles of statistical physics that predicts…
