In this chapter we discuss in a pedagogical way and from the very beginning the Mean Exponential Growth factor of Nearby Orbits (MEGNO) method, that has proven, in the last ten years, to be efficient to investigate both regular and chaotic components

Together with the variational indicators of chaos, the spectral analysis methods have also achieved great popularity in the field of chaos detection. The former are based on the concept of local exponential divergence. The latter are based on the num

We report an intrinsic relation between the mean exponential growth factor of nearby orbits (MEGNO) and the fast Lyapunov indicator (FLI), two variational methods that have been widely applied to stability issues in astronomy. For both continuous-tim

Presentamos un nuevo método para evaluar el comportamiento global de órbitas en un potencial dado, mediante el cómputo de la entropía del mapa de Poincaré para un conjunto dado de condiciones iniciales. Utilizamos este método para evaluar el gr

Los sistemas esféricos formados por estrellas con órbitas muy alargadas sufren la denominada inestabilidad de órbitas radiales a causa de la cual el sistema adquiere una órbita barrada. En este trabajo se estudian órbitas planas de estrellas en
