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 planets, Kepler-51b (Pb = 45.2 days) and Kepler-51c (Pc = 85.3 days), and one transiting planet candidate KOI-620.02 (P02 = 130.2 days), which lie close to a 1: 2: 3 resonance chain. Our analysis shows that their TTVs are consistently explained by the three-planet model, and constrains their masses as (Kepler-51b… 
PLANET HUNTERS. VII. DISCOVERY OF A NEW LOW-MASS, LOW-DENSITY PLANET (PH3 C) ORBITING KEPLER-289 WITH MASS MEASUREMENTS OF TWO ADDITIONAL PLANETS (PH3 B AND D)
We report the discovery of one newly confirmed planet (P = 66.06 days, RP = 2.68 ± 0.17 R⊕) and mass determinations of two previously validated Kepler planets, Kepler-289 b (P = 34.55 days, RP = 2.15
Discovery of a Third Transiting Planet in the Kepler-47 Circumbinary System
Of the nine confirmed transiting circumbinary planet systems, only Kepler-47 is known to contain more than one planet. Kepler-47 b (the “inner planet”) has an orbital period of 49.5 days and a radius
SECURE MASS MEASUREMENTS FROM TRANSIT TIMING: 10 KEPLER EXOPLANETS BETWEEN 3 AND 8 M ⊕ WITH DIVERSE DENSITIES AND INCIDENT FLUXES
We infer dynamical masses in eight multiplanet systems using transit times measured from Kepler's complete data set, including short-cadence data where available. Of the 18 dynamical masses that we
Kepler-90: Giant Transit-timing Variations Reveal a Super-puff
Exoplanet transit-timing variations (TTVs) caused by gravitational forces between planets can be used to determine planetary masses and orbital parameters. Most of the observed TTVs are small and
Mass determination of the 1:3:5 near-resonant planets transiting GJ 9827 (K2-135)
Context. Multiplanet systems are excellent laboratories to test planet formation models as all planets are formed under the same initial conditions. In this context, systems transiting bright stars
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
The mass of the Mars-sized exoplanet Kepler-138 b from transit timing
TLDR
The sizes and masses of three planets orbiting Kepler-138, a star much fainter and cooler than the Sun, are reported, determining that the mass of the Mars-sized inner planet, Kepler- 138 b, is Earth masses and its density is grams per cubic centimetre.
Kepler Planet Masses and Eccentricities from TTV Analysis
We conduct a uniform analysis of the transit timing variations (TTVs) of 145 planets from 55 Kepler multiplanet systems to infer planet masses and eccentricities. Eighty of these planets do not have
The effects of external planets on inner systems: multiplicities, inclinations and pathways to eccentric warm Jupiters
We study how close-in systems such as those detected by Kepler are affected by the dynamics of bodies in the outer system. We consider two scenarios: outer systems of giant planets potentially
Measurement of planet masses with transit timing variations due to synodic "chopping" effects
Gravitational interactions between planets in transiting exoplanetary systems lead to variations in the times of transit that are diagnostic of the planetary masses and the dynamical state of the

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.
