TL;DR: In this article, the physical parameters, transmission and emission spectra of the transiting extrasolar planet WASP-19b were measured using ground-based, multi-colour, broad-band photometric measurements.

TL;DR: In this paper, a new model for analyzing light curves of planetary transits when there are starspots on the stellar disc was developed, which combines the global minimization power of a genetic algorithm and the Bayesian statistical analysis of the Markov chain.

TL;DR: In this paper, the authors present time series photometric observations of 13 transits in the planetary systems WASP-24, WASP25 and WASP26, which have scatters of 0.5-1.2 mmag relative to their best-fitting geometric models.

TL;DR: In this article, the authors analyzed the planetary microlensing event MOA-2010-BLG-328 and showed that the microlens parallax signal, which determines the host mass and distance, is actually due to xallarap (source orbital motion) that is being misinterpreted as paralax.
