VERY LOW DENSITY PLANETS AROUND KEPLER-51 REVEALED WITH TRANSIT TIMING VARIATIONS AND AN ANOMALY SIMILAR TO A PLANET–PLANET …

K Masuda - The Astrophysical Journal, 2014 - iopscience.iop.org
We present an analysis of the transit timing variations (TTVs) in the multi-transiting planetary
system around Kepler-51 (KOI-620). This system consists of two confirmed transiting …

The Kepler-19 system: a transiting 2.2 R⊕ planet and a second planet detected via transit timing variations

S Ballard, D Fabrycky, F Fressin… - The Astrophysical …, 2011 - iopscience.iop.org
We present the discovery of the Kepler-19 planetary system, which we first identified from a

We present a detailed characterization of the Kepler-411 system (KOI 1781). This system
was previously known to host two transiting planets: one with a period of 3 days (R= 2.4 R⊕; …

KOI-142, the king of transit variations, is a pair of planets near the 2: 1 resonance

D Nesvorný, D Kipping, D Terrell… - The Astrophysical …, 2013 - iopscience.iop.org
The transit timing variations (TTVs) can be used as a diagnostic of gravitational interactions
between planets in a multi-planet system. Many Kepler Objects of Interest (KOIs) exhibit …

A dynamical analysis of the Kepler-80 system of five transiting planets

MG MacDonald, D Ragozzine… - The Astronomical …, 2016 - iopscience.iop.org

tremendous potential both individually and collectively for understanding the formation and …

All six planets known to orbit Kepler-11 have low densities

JJ Lissauer, D Jontof-Hutter, JF Rowe… - The Astrophysical …, 2013 - iopscience.iop.org
The Kepler-11 planetary system contains six transiting planets ranging in size from 1.8 to 4.2
times the radius of Earth. Five of these planets orbit in a tightly packed configuration with …

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

WD Cochran, DC Fabrycky, G Torres… - The Astrophysical …, 2011 - iopscience.iop.org
We report the detection of three transiting planets around a Sun-like star, which we
