Evidence for a planetary mass third body orbiting the binary star KIC 5095269 [PDF]

, 2017
In this paper, we report the evidence for a planetary mass body orbiting the close binary star KIC 5095269. This detection arose from a search for eclipse timing variations among the more than 2,000 eclipsing binaries observed by Kepler.

Multi-site campaign for transit timing variations of WASP-12 b: possible detection of a long-period signal of planetary origin

, 2013
The transiting planet WASP-12 b was identified as a potential target for transit timing studies because a departure from a linear ephemeris was reported in the literature. Such deviations could be caused by an additional planet in the system.

Investigating Transit Timing Variations in the Ultrashort Period Exoplanet WASP-19b

The Astronomical Journal
In this study, we present a comprehensive analysis of transit timing variations (TTVs) in the ultrashort-period gas giant WASP-19b, which orbits a G-type main-sequence star.

Transit Timing and Duration Variations for the Discovery and Characterization of Exoplanets

, 2017
Transiting exoplanets in multi-planet systems have non-Keplerian orbits which can cause the times and durations of transits to vary. The theory and observations of transit timing variations (TTV) and transit duration variations (TDV) are reviewed.

A Modified Kwee–Van Woerden Method for Eclipse Minimum Timing with Reliable Error Estimates

Galaxies, 2020
The Kwee–van Woerden (KvW) method used for the determination of eclipse minimum times has been a staple in eclipsing binary research for decades, due its simplicity and the independence of external input parameters, which also makes it well-suited to ...

TOI-4504: Exceptionally Large Transit Timing Variations Induced by Two Resonant Warm Gas Giants in a Three-planet System

The Astrophysical Journal Letters
We present a joint analysis of transit timing variations (TTVs) and Doppler data for the transiting exoplanet system TOI-4504. TOI-4504 c is a warm Jupiter-mass planet that exhibits the largest known TTVs, with a peak-to-node amplitude of ∼2 days, the ...

Constraining the Presence of Companion Planets in Hot Jupiter Planetary Systems Using Transit-timing Variation Observations from TESS

The Astrophysical Journal Supplement Series
The presence of another planetary companion in a transiting exoplanet system can impact its transit light curve, leading to sinusoidal transit-timing variations (TTV).
