Splitting Methods for High-Precision Integration in Dynamical Astronomy

A. Farres, S. Blanes, F. Casas, J. Laskar and A. Murua

Abstract
In this talk we will present new families of splitting methods designed for the numerical integration of near-integrable Hamiltonian systems, with a particular interest on planetary N-body problems. We will use a Newtonian model for the motion of the planetary system and perform an extensive comparison between various high-order symplectic splitting methods. The comparisons will be made in both, Jacobi and Heliocentric coordinates.
