Motion in Aubry's galaxy

Classical Physics 2025-09-23 v1

Abstract

The dynamics of a test particle in the field of a model galaxy proposed by Serge Aubry is studied by a combination of theory and numerical computation. Regimes of near-integrable behaviour and almost perfect chaos are found. A proposed explanation for the latter is sketched. Thoughts are presented on the implications of the analysis for galaxies.
