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… 
ARE THE KEPLER NEAR-RESONANCE PLANET PAIRS DUE TO TIDAL DISSIPATION?
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
TLDR
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.
