Using a Newtonian model of the Solar System with all 8 planets, we perform extensive tests on various symplectic integrators of high orders, searching for the best splitting scheme for long term studies in the Solar System. These comparisons are made in Jacobi and heliocentric coordinates and the implementation of the algorithms is fully detailed for practical use. We conclude that high order integrators should be privileged, with a preference for the new $$(10,6,4)$$ method of Blanes et al… Expand
A study of symplectic integrators for planetary system problems: error analysis and comparisons
The symplectic Wisdom-Holman map revolutionized long-term integrations of planetary systems. There is freedom in such methods of how to split the Hamiltonian and which coordinate system to employ,Expand

Dynamic stability of the Solar System: Statistically inconclusive results from ensemble integrations
Due to the chaotic nature of the Solar System, the question of its long-term stability can only be answered in a statistical sense, for instance, based on numerical ensemble integrations of nearbyExpand
Dedicated symplectic integrators for rotation motions
We propose to use the properties of the Lie algebra of the angular momentum to build symplectic integrators dedicated to the Hamiltonian of the free rigid body. By introducing a dependence of theExpand
Are long-term N-body simulations reliable?
$N$-body integrations are used to model a wide range of astrophysical dynamics, but they suffer from errors which make their orbits diverge exponentially in time from the correct orbits. Over longExpand
Symplectic orbit propagation based on Deprit’s radial intermediary
This work presents the development of symplectic integrators of different orders for spacecraft orbit propagation, and shows that these integrators are more accurate and substantially faster than Runge-Kutta-based methods. Expand
Variational and symplectic integrators for satellite relative orbit propagation including drag
Orbit propagation algorithms for satellite relative motion relying on Runge–Kutta integrators are non-symplectic—a situation that leads to incorrect global behavior and degraded accuracy. Thus,Expand
New Integration Methods for Perturbed ODEs Based on Symplectic Implicit Runge–Kutta Schemes with Application to Solar System Simulations
A family of integrators, flow-composed implicit Runge–Kutta methods, for perturbations of nonlinear ordinary differential equations, consisting of the composition of flows of the unperturbed part alternated with one step of an implicitrunge–kutta (IRK) method applied to a transformed system, with potential application to long-term solar system simulations.

A hybrid symplectic integrator that permits close encounters between massive bodies
Mixed-variable symplectic integrators exhibit no long-term accumulation of energy error, beyond that owing to round-off, and they are substantially faster than conventional N-body algorithms. ThisExpand
