Approximate integrals of motion

Bienaymé, O. and Traven, G. LU (2013) In Astronomy and Astrophysics 549.
Abstract

We determine approximate numerical integrals of motion of 2D symmetric Hamiltonian systems. We detail for a few gravitational potentials the conditions under which quasi-integrals are obtained as polynomial series. We show that each of these potentials has a wide range of regular orbits that are accurately modelled with a unique approximate integral of motion.
