Transiting exoplanetary systems are surpassingly important among the planetary systems since they provide the widest spectrum of information for both the planet and the host star. If a transiting planet is on an eccentric orbit, the duration of transits T D is sensitive to the orientation of the orbital ellipse relative to the line of sight. The precession of the orbit results in a systematic variation in both the duration of individual transit events and the observed period between successive…

Transit Timing and Duration Variations for the Discovery and Characterization of Exoplanets
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
Stellar Proper Motion and the Timing of Planetary Transits
Duration and period of transits in extrasolar planetary systems can exhibit long-term variations for a variety of reasons. Here we investigate how systemic proper motion, which steadily re-orients
Parametrized post-Newtonian secular transit timing variations for exoplanets ∗
Ground-based and space-borne observatories used for studying exoplanet transits now and in the future will considerably increase the number of exoplanets known from transit data and the precision of
Detecting general relativistic orbital precession in transiting hot Jupiters
Both classical and relativistic weak-field and slow-motion perturbations to planetary orbits can be treated as perturbative corrections to the Keplerian model. In particular, tidal forces and General

Context. Transiting planetary systems allow us to extract geometrical information, e.g., the anglebetween the orbital angular momentum and the stellar spin, that can be used to discriminate among
The observed properties of transiting exoplanets are an exceptionally rich source of information that allows us to understand and characterize their physical properties. Unfortunately, only a
Oscillations of relative inclination angles in compact extrasolar planetary systems
The Kepler Mission has detected dozens of compact planetary systems with more than four transiting planets. This sample provides a collection of close-packed planetary systems with relatively little
Planetary transit timing variations induced by stellar binarity: the light travel time effect
Context. Since the discovery of the first transiting extrasolar planet, transit timing has been recognized as a powerful method to discover and characterize additional planets in these systems.
Challenges of Detecting Unseen Planetary Companions with Transit Timing Variations
Both ground- and space-based transit observatories are poised to significantly increase the number of known transiting planets and the number of precisely measured transit times. The variation in a
TESS Transit Timing of Hundreds of Hot Jupiters
We provide a database of transit times and updated ephemerides for 382 planets based on data from the NASA Transiting Exoplanet Survey Satellite (TESS) and previously reported transit times, which


Orbital Perturbations of Transiting Planets: A Possible Method to Measure Stellar Quadrupoles and to Detect Earth-Mass Planets
The recent discovery of a planetary transit in the star HD 209458, and the subsequent highly precise observation of the transit light curve with Hubble Space Telescope, is encouraging to search for
Using long-term transit timing to detect terrestrial planets
ABSTRACT We propose that the presence of additional planets in extrasolar planetary systemscan be detected by long-term transit timing studies. If a transiting planet is on aneccentric orbit then the

We report the detection of transits by the 3.1MJup companion to the V=8.17 G0V star HD 17156. The transit was observed by three independant observers on Sept. 9/10, 2007 (two in central Italy and one

Detection of Planetary Transits Across a Sun-like Star.
High-precision, high-cadence photometric measurements of the star HD 209458 are reported, which is known from radial velocity measurements to have a planetary-mass companion in a close orbit and the detailed shape of the transit curve due to both the limb darkening of thestar and the finite size of the planet is clearly evident.

On detecting terrestrial planets with timing of giant planet transits
The transits of a distant star by a planet on a Keplerian orbit occur at time intervals exactly equal to the orbital period. If a second planet orbits the same star, the orbits are not Keplerian and

The Use of Transit Timing to Detect Terrestrial-Mass Extrasolar Planets
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.
