At a GlanceAI

Analytical framework to quantify how close exoplanet pairs are to mean-motion resonances and what that implies for their dynamics.

SummaryAI

The work provides an analytical way to assess how near observed exoplanetary systems lie to mean-motion resonances, rather than relying only on numerical experiments or qualitative labels. By focusing on “proximity” to resonance, it helps interpret whether resonant dynamics may be shaping the architecture and long-term behavior of multi-planet systems. Such diagnostics are useful for connecting observations (period ratios) to underlying dynamical states and for identifying systems where resonance effects are likely important.
