At a GlanceAI
Assesses orbital stability of planetary pairs captured in first-order mean-motion resonances.
SummaryAI
Many planet pairs are expected to be trapped in first-order mean-motion resonances during migration, but whether such configurations remain stable is a key question for planet formation and observed system architectures. This study examines the orbital stability of planets in these resonances and identifies what conditions allow resonant trapping to persist versus break down. The results help interpret why some observed planetary systems show resonant chains while many sit just outside exact resonance. It also informs how long resonant configurations can survive as planetary systems evolve.
