Apsidal alignment and anti-alignment of planets in mean-motion resonance: disc-driven migration and eccentricity driving

JT Laune, L Rodet, D Lai - Monthly Notices of the Royal …, 2022 - academic.oup.com
Planets migrating in their natal discs can be captured into mean-motion resonance (MMR),
in which the planets' periods are related by integer ratios. Recent observations indicate that …

The orbit of Aegaeon and the 7: 6 Mimas-Aegaeon resonance
