The Kepler mission is dramatically increasing the number of planets known in multi-planetary systems. Many adjacent planets have orbital period ratios near resonant values, with a tendency to be larger than required for exact first-order mean-motion resonances. This feature has been shown to be a natural outcome of orbital circularization of resonant planetary pairs due to star–planet tidal interactions. However, this feature holds in multi-planetary systems with periods longer than 10 days, in… 
The multiple-planet systems discovered by the Kepler mission show an excess of planet pairs with period ratios just wide of exact commensurability for first-order resonances like 2:1 and 3:2. In
Disruption of co-orbital (1:1) planetary resonances during gas-driven orbital migration
Planets close to their stars are thought to form farther out and migrate inward due to angular momentum exchange with gaseous protoplanetary disks. This process can produce systems of planets in
Formation of a planetary Laplace resonance through migration in an eccentric disk
Context. Orbital mean motion resonances in planetary systems originate from dissipative processes in disk-planet interactions that lead to orbital migration. In multi-planet systems that host giant
Dynamical rearrangement of super-Earths during disk dispersal - I. Outline of the magnetospheric rebound model
Context. The Kepler mission has discovered that close-in super-Earth planets are common around solar-type stars. They are often seen together in multiplanetary systems, but their period ratios do not
Radial Migration of Gap-opening Planets in Protoplanetary Disks. II. The Case of a Planet Pair
When two planets are born in a protoplanetary disk, they may enter into mean-motion resonance as a consequence of convergent planetary migration. The formation of mean-motion resonances is important
On the orbital evolution of a pair of giant planets in mean motion resonance
Pairs of extrasolar giant planets in a mean motion commensurability are common with 2:1 resonance occurring most frequently. Disc-planet interaction provides a mechanism for their origin. However,
Evolutionary outcomes for pairs of planets undergoing orbital migration and circularization: second-order resonances and observed period ratios in Kepler's planetary systems
In order to study the origin of the architectures of low mass planetary systems, we perform numerical surveys of the evolution of pairs of coplanar planets in the mass range $(1-4)\
The Origin of Systems of Tightly Packed Inner Planets with Misaligned, Ultra-short-period Companions
Ultra-short-period planets provide a window into the inner edge of the parameter space occupied by planetary orbits. In one particularly intriguing class of multiplanet systems, the
Tidal dissipation and the formation of Kepler near-resonant planets
Multiplanetary systems detected by the Kepler mission present an excess of planets close to first-order mean-motion resonances (2:1 and 3:2), but with a period ratio slightly higher than the resonant
A Population of planetary systems characterized by short-period, Earth-sized planets
From a statistical analysis of the planet candidate catalog from NASA’s Kepler mission, a population of planetary systems characterized by a unique system architecture is identified, likely indicating a different branch in their evolutionary past relative to the typical Kepler system.


Period ratios in multi-planetary systems discovered by Kepler are consistent with planet migration
The Kepler planet candidates are an interesting testbed for planet formation scenarios. We present results from N-body simulations of multi-planetary systems that resemble those observed by Kepler.
Planets near Mean-motion Resonances
The multiple-planet systems discovered by the Kepler mission exhibit the following feature: planet pairs near first-order mean-motion resonances prefer orbits just outside the nominal resonance,
Resonant Repulsion of Kepler Planet Pairs
Planetary systems discovered by the Kepler space telescope exhibit an intriguing feature. While the period ratios of adjacent low-mass planets appear largely random, there is a significant excess of
Tidal interactions in multi-planet systems
We study systems of close orbiting planets evolving under the influence of tidal circularization. It is supposed that a commensurability forms through the action of disk induced migration and orbital
The dynamical origin of the multi-planetary system HD 45364
The recently discovered planetary system HD 45364, which consists of a Jupiter and Saturn-mass planet, is very likely in a 3:2 mean motion resonance. The standard scenario for forming planetary
Almost All of Kepler's Multiple-planet Candidates Are Planets
We present a statistical analysis that demonstrates that the overwhelming majority of Kepler candidate multiple transiting systems (multis) indeed represent true, physically associated transiting
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 Detection and Characterization of a Nontransiting Planet by Transit Timing Variations
A planetary system with two confirmed planets and one candidate planet discovered with the publicly available data for KOI-872, reminiscent of the orderly arrangement within the solar system, with nearly coplanar and circular orbits.
Planetary Torques as the Viscosity of Protoplanetary Disks
We revisit the idea that density wave wakes of planets drive accretion in protostellar disks. The effects of many small planets can be represented as a viscosity if the wakes damp locally but the
On the migration-induced resonances in a system of two planets with masses in the Earth mass range
We investigate orbital resonances expected to arise when a system of two planets, with masses in the range 1–4 M⊕, undergoes convergent migration while embedded in a section of gaseous disc where the
