The study of orbital resonances allows for the constraint of planetary properties of compact
systems. We can predict a system's resonances by observing the orbital periods of the …

HD 110067 is the brightest star known to have six transiting planets. Each adjacent pair of
planets has a period ratio that is nearly equal to a ratio of small integers, suggesting the …

We describe a method of determining three-body and four-body Laplace-like phase angles
with the potential to librate about a mean value in multiplanet extrasolar systems. Unlike in …

Super-Earth b and sub-Neptunes c and d are orbiting about the M-dwarf TOI-270 in that
order from the star. Their global resonant chain (3: 5, 1: 1, 2: 1) is extremely surprising …

We revisit 77 relaxed (extra) solar multibody (sub) systems containing 2-9 bodies orbiting
about gravitationally dominant central bodies. Most of the multiplanet systems (68) have …
