A Keplerian-based Hamiltonian Splitting for Gravitational $N$-body Simulations

G. Gonçalves Ferrari, T. Boekholt, S. F. Portegies Zwart

We developed a Keplerian-based Hamiltonian splitting for solving the gravitational $N$-body problem. This splitting allows us to approximate the solution of a general $N$-body prob…
