The Hénon-Heiles equation is a nonlinear nonintegrable Hamiltonian system where the potential energy function is defined by a polar coordinate system. It was developed by Michel Hénon and Carl Heiles for modelling galactic dynamics.
Description
While at Princeton in 1962, Hénon and Heiles worked on the non-linear motion of a star around a galactic center where the motion is restricted to a plane.
In 1964 they have published an article titled 'The applicability of the third integral of motion: Some numerical experiments'.
Their original idea was to find a third integral of motion in a galactic dynamics. For that purpose they have taken a simplified two-dimensional nonlinear axi-symmetric potential and found that the third integral exist only for a limited number of initial conditions.
In the modern perspective these initial conditions which doesn't have the third integral motion are called chaotic orbits.
