Orbital Stability of Apsidally Aligned Planetary Systems
Gabriel Teixeira Guimarães, Eiichiro Kokubo
The dynamical stability of compact planetary systems is known to depend strongly on orbital eccentricities, but the physical role of apsidal alignment remains poorly understood. We…
Revisiting the dynamics of the Prometheus-Pandora system
Demétrio Tadeu Ceccatto, Nelson Callegari, Gabriel Teixeira Guimarães
This study revisits the dynamics of Prometheus and Pandora. The analysis focuses on their current orbits and considers mutual perturbations and the non-spherical shape of Saturn. N…
Orbital Dynamics of Atlas (S XV): Its Current Orbit and the Recent Past
Demétrio Tadeu Ceccatto, Nelson Callegari, Gabriel Teixeira Guimarães +1
This study comprehensively analyzes Atlas's current orbit, focusing on the secular and resonant perturbations caused by Prometheus, Pandora, and Saturn's oblateness. We performed n…
Chaotic diffusion in the action and frequency domains: estimate of instability times
Gabriel Teixeira Guimarães, Tatiana Alexandrovna Michtchenko
Purpose: Chaotic diffusion in the non-linear systems is commonly studied in the action framework. In this paper, we show that the study in the frequency domain provides good estima…
