Confirming Resonance in Three Transiting Systems

open access: yesThe Astronomical Journal, 2023
Although resonant planets have orbital periods near commensurability, resonance is also dictated by other factors, such as the planets’ eccentricities and masses, and therefore must be confirmed through a study of the system’s dynamics.
