T1 - Transit timing variations in eccentric hierarchical triple exoplanetary systems T2 - I. Methods. Transit least-squares survey III. Lee et al. "That is the promise of transit timing variations," Ballard said. Measurements over long periods can reveal minute changes in a planets masses ! Perturbations on the time scale of the orbital period of the perturber AU - Borkovits, T. AU - Csizmadia, Sz AU - … Transit timing variations of Kepler-410Ab were already reported in a few papers. Whether they're Earth-like, I don't know. Confirmation of four multiple planet systems by a Fourier-domain study of anticorrelated transit timing variations The Harvard community has made this article openly available. We report the detection of a system of two transiting planets (Kepler-9b and 9c) showing transit timing variations (TTVs) (6, 7). We analyze the transit timing variations (TTV) obtained by the Kepler mission for 22 sub-Jovian planet pairs (19 published, 3 new) that lie close to mean motion resonances. Their semi-amplitude is about 14.5 minutes. An illustration of the difference in mid-transit times between single- and multiplanetary systems can be seen on figure2. Transit Timing Variations of WASP-3b and WASP-10b Credit: NASA, ESA, and G. Bacon (STScI), STScI-2006-34 Analysis of O-C (observed – calculated) diagrams – TTV (Steffen et al. transit early or late ! Transit-timing variation is a method for detecting exoplanets by observing variations in the timing of a transit. Transit Timing Variations (TTV) 法 • TTV法: TTVの検出から惑星を発見 (物理量を測定) • 特徴 – トランジットしていない(傾いた)惑星を発見可能 – 複数の惑星がトランジットしている系において、お互いの 質量や軌道を決定することが可能 TTVs are particularly sensitive to gravitational perturbations from additional planets orbiting the host star ( 2 – 4 ) and distant large moons orbiting the transiting planet ( 5 – 7 ). This provides an extremely sensitive method capable of detecting additional planets in the system with masses potentially as small as that of Earth. We present 22 new times of mid-transit that confirm the existence of transit timing variations, and are well fitted by a quadratic ephemeris with period decay dP/dt = −9.2 ± 1.1 ms yr −1. Thus, the aim of this paper is to discuss the plausibility of transit timing variations (TTVs) on the Qatar-1 system by means of primary transit light curves analysis. Transit timing observations from Kepler: III. Timing Variations @ YETI" (TTV@YETI) project which is dedicated to detect and characterize signals of transit timing variations. In this Letter we present observations of recent HAT‐P‐13b transits. Agol for useful discussions about the transit timing variations method, and the members of the Board of Examiners, Olivier Absil, Laetitia Delrez, Fran Pozuelos, and Valerie Van Grootel, for the time they will devote to this Master thesis. We present 22 new times of mid-transit that confirm the existence of transit timing variations, and are well fitted by a quadratic ephemeris with period decay dP/dt = -9.2 ± 1.1 ms yr-1.
