VizieR Online Data Catalog: Kepler eclipse timing variation analyses (Borkovits+, 2015)
Abstract
The present version of the Kepler EB Catalog (http://keplerebs.villanova.edu/) (Conroy et al. 2014, J/AJ/147/45) contains 2645 EBs. We selected our systems from that sample. We started our search for the appropriate compact hierarchical triple stars (CHTs) with the construction of O-C ("observed minus calculated" eclipse times) curves for the primary and, when possible, the secondary, eclipses for all 2645 binaries. At the same time, we also produced folded light curves for each binary. In all, we found some 400 binary systems that have interesting (i.e. non-linear) O-C curves (see also Rappaport et al. 2013ApJ...768...33R; Conroy et al. 2014, J/AJ/147/45). However, most of these tend to be either parabolically shaped or have sinusoidal shapes with a period comparable to, or longer than, the Kepler mission. The majority of these are probably triple systems, as indicated by the presence of perturbations that are likely due to a third body in the system, but are otherwise not particularly interesting for this study. We then restricted our attention only to the subset of these systems.
