The number of multiple-planet systems known to be involved in mean motion conmensurabilities has increased significantly since the Kepler mission. Although most correspond to two-planet resonances, multiple resonances have also been found. The Laplace resonance is a particular case of a three-body resonance in which the period ratio between consecutive pairs is n1/n2 ∼ n2/n3 ∼ 2/1. It is not clear how this triple resonance acts to stabilize (or not) the system. The most reliable extrasolar…

DYNAMICAL EVOLUTION OF MULTI-RESONANT SYSTEMS: THE CASE OF GJ 876
The GJ 876 system was among the earliest multi-planetary detections outside of the Solar System, and has long been known to harbor a resonant pair of giant planets. Subsequent characterization of the
New Constraints on Gliese 876—Exemplar of Mean-motion Resonance
Gliese 876 harbors one of the most dynamically rich and well-studied exoplanetary systems. The nearby M4V dwarf hosts four known planets, the outer three of which are trapped in a Laplace mean-motion
The orbital configuration of the two interacting Jupiters in HD 155358 system
Recent observation reveals two interacting Jupiters possibly trapped in a 2: 1 mean motion resonance (MMR) around the star HD 155358. For the 2:1 MMR, Beauge et al. found that as long as the orbital

We describe a comprehensive model for systems locked in the Laplace resonance. The framework is based on the simplest possible dynamical structure provided by the Keplerian problem perturbed by the
Resonant capture of multiple planet systems under dissipation and stable orbital configurations
Abstract Migration of planetary systems caused by the action of dissipative forces may lead the planets to be trapped in a resonance. In this work we study the conditions and the dynamics of such
Near Mean-motion Resonances in the System Observed by Kepler: Affected by Mass Accretion and Type I Migration
The Kepler mission has released over 4496 planetary candidates, among which 3483 planets have been confirmed as of 2017 April. The statistical results of the planets show that there are two peaks
A DETAILED ANALYSIS OF THE HD 73526 2:1 RESONANT PLANETARY SYSTEM
We present six years of new radial velocity data from the Anglo-Australian and Magellan Telescopes on the HD 73526 2:1 resonant planetary system. We investigate both Keplerian and dynamical
Possible solution to the riddle of HD 82943 multiplanet system: the three-planet resonance 1:2:5?
We carry out a new analysis of the published radial velocity data for the planet-hosting star HD82943. We include the recent Keck/HIRES measurements as well as the aged but much more numerous CORALIE
TOI-216: Resonant Constraints on Planet Migration
TOI-216 is a pair of close-in planets with orbits deep in the 2:1 mean motion resonance. The inner Neptune-class planet (TOI-216b) is near 0.12 au (orbital period P b ≃ 17 days) and has a substantial

Can GJ 876 host four planets in resonance?
