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…

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
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


Modelling the high-eccentricity planetary three-body problem. Application to the GJ876 planetary system
The discovery of extrasolar planets located in the vicinity of mean-motion commensurabilities has opened a new arena for the study of resonance capture and its possible role in the dynamical
Can GJ 876 host four planets in resonance?
Prior to the detection of its outermost Uranus-mass object, it had been suggested that GJ 876 could host an Earth-sized planet in a 15-day orbit. Observation, however, did not support this idea, but
Modeling the resonant planetary system GJ 876
The two planets about the star GJ 876 appear to have undergone extensive migration from their point of origin in the protoplanetary disk – both because of their close proximity to the star (30 and 60
Dynamics of the Giant Planets of the Solar System in the Gaseous Protoplanetary Disk and Their Relationship to the Current Orbital Architecture
We study the orbital evolution of the four giant planets of our solar system in a gas disk. Our investigation extends the previous works by Masset & Snellgrove and Morbidelli & Crida, which focused
Trapping in three-planet resonances during gas-driven migration
We study the establishment of three-planet resonances—similar to the Laplace resonance in the Galilean satellites—and their effects on the mutual inclinations of the orbital planes of the planets,
Reliability of orbital fits for resonant extrasolar planetary systems: the case of HD82943
We perform a statistical study of the process of orbital determination of the HD82943 extrasolar planetary system, using the current observational data set of N = 165 radial velocity (RV)
Architecture and Dynamics of Kepler's Candidate Multiple Transiting Planet Systems
About one-third of the ∼1200 transiting planet candidates detected in the first four months of Kepler data are members of multiple candidate systems. There are 115 target stars with two candidate
The recent Kepler discovery of KOI-152 reveals a system of three hot super-Earth candidates that are in or near a 4:2:1 mean motion resonance. It is unlikely that they formed in situ; the planets
Orbital structure of the GJ876 extrasolar planetary system based on the latest Keck and HARPS radial velocity data
We use full available array of radial velocity data, including recently published HARPS and Keck observatory sets, to characterize the orbital configuration of the planetary system orbiting GJ876.
Dynamics of Systems of Two Close Planets
Abstract In connection with the study of newly formed protoplanetary embryos in the early Solar System, we study the dynamics of a pair of interacting planets orbiting a Sun. By examining the
