Abstract

Computing the chemical composition of planet is a growing need for planetary formation models. Previous works have been investigating the chemical composition of planet, combining dynamical process of planetary formation and chemistry. However, either these studies have only focused on the volatile content of the planets (CO,H2O,CO2,CH4…) either the composition of the planets have been determined in a non self-consistent manner.  We present here results of calculations of chemical compositions of planets with the combination of the planetary formation model of Alibert et al.  (2013, and references therein) and the condensation sequence theory.  We derive the most important elements for which the knowledge of the stellar abundance is needed to compute the composition of the planet that can be formed. To do so, we vary the initial stellar composition in the chemical model, and investigate possible correlations between different ratios in stars and planets.
