Advances in exoplanet science from Kepler
TLDR
Kepler has provided us with the authors' first look at the typical characteristics of planets and planetary systems for planets with sizes as small as, and orbits as large as, those of Earth.
Dynamical Stability of Planetary Systems
The study of dynamical stability in planetary systems has become possible during the last few decades due to the development of numerical methods for long-term integrations of N-body systems. Since
Introduction: The Hunt for Extra-Solar Planets
Since the dawn of civilisation we have looked up to the stars, wondering whether other worlds exist and what they might look like. In the last few decades, developments in instrumentation and
Phase Curves of the Kepler-11 Multi-planet System
The Kepler mission has allowed the detection of numerous multi-planet exosystems where the planetary orbits are relatively compact. The first such system detected was Kepler-11 which has six known
Understanding the assembly of Kepler's tightly-packed planetary systems
Abstract The Kepler mission has recently discovered a number of exoplanetary systems, such as Kepler 11, in which ensembles of several planets are found in very closely packed orbits. These systems
SPIN–ORBIT MISALIGNMENT AS A DRIVER OF THE KEPLER DICHOTOMY
During its five-year mission, the Kepler spacecraft has uncovered a diverse population of planetary systems with orbital configurations ranging from single-transiting planets to systems of multiple
Doppler Monitoring of five K2 Transiting Planetary Systems
In an effort to measure the masses of planets discovered by the NASA K2 mission, we have conducted precise Doppler observations of five stars with transiting planets. We present the results of a

TLDR
The Kepler Mission has made significant progress measuring the prevalence of exoplanets orbiting within one astronomical unit of their host stars in support of the National Aeronautics and Space Administration’s long-term goal of finding habitable environments beyond the solar system.

A closely packed system of low-mass, low-density planets transiting Kepler-11
TLDR
Kepler spacecraft observations of a single Sun-like star are reported that reveal six transiting planets, five with orbital periods between 10 and 47 days and a sixth planet with a longer period, among the smallest for which mass and size have both been measured.
Kepler-36: A Pair of Planets with Neighboring Orbits and Dissimilar Densities
TLDR
Another violation of the orbit-composition pattern is reported: two planets orbiting the same star with orbital distances differing by only 10% and densities differing by a factor of 8, likely a rocky “super-Earth,” whereas the other is more akin to Neptune.
MINIMUM RADII OF SUPER-EARTHS: CONSTRAINTS FROM GIANT IMPACTS
The detailed interior structure models of super-Earth planets show that there is degeneracy in the possible bulk compositions of a super-Earth at a given mass and radius, determined via radial
A dynamical analysis of the Kepler-11 planetary system
The Kepler-11 planetary system hosts at least six transiting super-Earth planets detected through the precise photometric observations of the Kepler mission (Lissauer et al.). In this paper, we
The CoRoT-7 planetary system: two orbiting super-Earths
We report on an intensive observational campaign carried out with HARPS at the 3.6 m telescope at La Silla on the star CoRoT-7. Additional simultaneous photometric measurements carried out with the
A super-Earth transiting a nearby low-mass star
TLDR
Observations of the transiting planet GJ’1214b are reported, finding that the planetary mass and radius are consistent with a composition of primarily water enshrouded by a hydrogen–helium envelope that is only 0.05% of the mass of the planet.
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
Kepler-9: A System of Multiple Planets Transiting a Sun-Like Star, Confirmed by Timing Variations
TLDR
Two Saturn-size planets show variations in the times they take to transit their star due to gravitational interaction, and six radial-velocity observations show that these two planets are the most massive objects orbiting close to the star and substantially improve the estimates of their masses.
The Use of Transit Timing to Detect Terrestrial-Mass Extrasolar Planets
TLDR
This work shows that timing measurements between successive transits will allow for the detection of additional planets in the system (not necessarily transiting) by their gravitational interaction with the transiting planet.
Kepler-18b, c, and d: A System of Three Planets Confirmed by Transit Timing Variations, Light Curve Validation, Warm-Spitzer Photometry, and Radial Velocity Measurements
We report the detection of three transiting planets around a Sun-like star, which we designate Kepler-18. The transit signals were detected in photometric data from the Kepler satellite, and were
