TL;DR: In this article, the authors reported the discovery of 96 new infrared open clusters and stellar groups and derived their fundamental parameters such as reddening, distance, and age by fitting the solar-metallicity Padova isochrones to the color-magnitude diagrams.

TL;DR: In this paper, a new method for confirming transiting planets based on the combination of transit timing variations (TTVs) and dynamical stability is presented. But the method is not suitable for the detection of all the transiting candidates.

TL;DR: In this article, the authors performed a transit timing analysis of the Kepler planet candidates and found that at least 11% of the candidates currently suitable for TTV analysis show evidence suggestive of TTVs, representing at least 65 TTV candidates.
