Time variation of Kepler transits induced by stellar spots - a way to distinguish between prograde and retrograde motion. II. Application to KOIs [PDF]
Mazeh, Holczer, and Shporer (2015) have presented an approach that can, in principle, use the derived transit timing variation (TTV) of some transiting planets observed by the $Kepler$ mission to distinguish between prograde and retrograde motion of ...

Transit timing variation and activity in the WASP-10 planetary system
Transit timing analysis may be an effective method of discovering additional bodies in extrasolar systems which harbour transiting exoplanets. The deviations from the Keplerian motion, caused by mutual gravitational interactions between planets, are ...

How to determine an exomoon's sense of orbital motion [PDF]
We present two methods to determine an exomoon's sense of orbital motion (SOM), one with respect to the planet's circumstellar orbit and one with respect to the planetary rotation. Our simulations show that the required measurements will be possible with

High-precision photometry of WASP-12 b transits
The transiting extrasolar planet WASP-12 b was found to be one of the most intensely irradiated exoplanets. It is unexpectedly bloated and is losing mass that may accrete into the host star.

Practical suggestions on detecting exomoons in exoplanet transit light curves
The number of known transiting exoplanets is rapidly increasing, which has recently inspired significant interest as to whether they can host a detectable moon. Although there has been no such example where the presence of a satellite was proven, several

Searching for Transit Timing Variations in Young Transiting Systems
The discovery of young (4 σ ), although differences in methodology make a totally fair comparison challenging. We show that spots have a weak-to-negligible impact on our results, and similarly cannot explain the higher TTV fraction.

The 8 Micron Phase Variation of the Hot Saturn HD 149026b [PDF]
We monitor the star HD 149026 and its Saturn-mass planet at 8.0 micron over slightly more than half an orbit using the Infrared Array Camera (IRAC) on the Spitzer Space Telescope. We find an increase of 0.0227% +/- 0.0066% (3.4 sigma significance) in the

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

Doomed Worlds. II. Reassessing Suggestions of Orbital Decay for TrES-5 b
TrES-5 b is one of only three ultrahot Jupiters with suggestions of a possibly decreasing orbital period that have persisted through multiple independent analyses.

Photometric Investigation of Hot Exoplanets: TrES-3b and Qatar-1b [PDF]
New photometric follow-up observations of exoplanet transits of 'hot Jupiters' TrES-3b and Qatar-1b are presented. Weighted mean values of the solutions of light curves in R-fiter for both planetary systems are reported and compared with the previous ...
