First-order mean motion resonances in two-planet systems: general analysis and observed systems

Abstract:

This paper focuses on two-planet systems in a first-order (q + 1): q mean motion resonance and undergoing type-Imigration in a disc.We present a detailed analysis of the resonance valid for any value of q. Expressions for the equilibrium eccentricities, mean motions, and departure from exact resonance are derived in the case of smooth convergent migration. We show that this departure, not assumed to be small, is such that the period ratio normally exceeds but can also be less than (q + 1)/q. ...
