Scientific paper

We present an adaptation of the Poincare model of core-mantle interaction (Poincare 1910, Touma & Wisdom 2001) to the rotation of Mercury, in which the planet is seen as composed of a rigid mantle and an elliptical liquid core. Thanks to a Hamiltonian formulation, we perform extensively both an analytical (Lie transforms) and a numerical analysis of this 4-degree of freedom problem. This allows us to highlight a long-term behavior of the obliquity, the consequences of the proximity of a resonance between the spin frequency of Mercury and the free core nutation, and also the influence of the shape of the core. Moreover, we note that the convergence rate of the Lie transforms algorithm strongly depends on the shape of the core.
