Application of transit timing variation method (TTV) to exoplanet system TrES-3 [PDF]

open access: goldВісник Астрономічної школи, 2015
On the basis of the original photometric data, the light curves of several transits in the exoplanet system TrES-3 were simulated by Monte Carlo method. Using these curves, the estimates of precise values of mid-transit time were calculated to assess the

Detection of Earth-mass and super-Earth Trojan planets using transit timing variation method [PDF]

open access: closedCelestial Mechanics and Dynamical Astronomy, 2013
We have carried out an extensive study of the possibility of the detection of Earth-mass and super-Earth Trojan planets using transit timing variation method with the Kepler space telescope.

FAST INVERSION METHOD FOR DETERMINATION OF PLANETARY PARAMETERS FROM TRANSIT TIMING VARIATIONS [PDF]

open access: greenThe Astrophysical Journal, 2010
The transit timing variation (TTV) method relies on monitoring changes in timing of transits of known exoplanets. Non-transiting planets in the system can be inferred from TTVs by their gravitational interaction with the transiting planet. The TTV method

On the detection of (habitable) super-Earths around low-mass stars using Kepler and transit timing variation method [PDF]

open access: closedCelestial Mechanics and Dynamical Astronomy, 2011
We present the results of an extensive study of the detectability of Earth-sized planets and super-Earths in the habitable zones of cool and low-mass stars using transit timing variation method.

The Advantages of Global Photometric Models in Fitting Transit Variations [PDF]

open access: yesThe Astronomical Journal, 2023
Estimation of planetary orbital and physical parameters from light-curve data relies heavily on the accurate interpretation of Transit Timing Variation (TTV) measurements.

Alleviating the transit timing variation bias in transit surveys. I. RIVERS: Method and detection of a pair of resonant super-Earths around Kepler-1705 [PDF]

open access: yesAstronomy & Astrophysics, 2021
Transit timing variations (TTVs) can provide useful information for systems observed by transit, as they allow us to put constraints on the masses and eccentricities of the observed planets, or even to constrain the existence of non-transiting companions.

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

open access: yesThe 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).

Revisiting TrES-5 b: departure from a linear ephemeris instead of short-period transit timing variation [PDF]

open access: yesAstronomy & Astrophysics, 2021
The orbital motion of the transiting hot Jupiter TrES-5 b was reported to be perturbed by a planetary companion on a nearby orbit. Such compact systems do not frequently occur in nature, and learning their orbital architecture could shed some light on ...

Transit Depth Variations Reveal TOI-216 b to be a Super-puff

open access: yesThe Astronomical Journal, 2023
The planets of the TOI-216 system have been previously observed to exhibit large transit-timing variations, which enabled precise mass characterization of both transiting planets.

Constraining the Densities of the Three Kepler-289 Planets with Transit Timing Variations

open access: yesThe Astronomical Journal, 2023
Kepler-289 is a three-planet system containing two sub-Neptunes and one cool giant planet orbiting a young, Sun-like star. All three planets exhibit transit timing variations (TTVs), with both adjacent planet pairs having orbital periods close to the 2:1
