Q1-11 Kepler light curve of KIC 4862625

The planet was discovered by volunteers searching the first six Quarters of publicly available Kepler data as part of the Planet Hunters citizen science project. Transits of the planet across the larger and brighter of the eclipsing stars are detectable by visual inspection every ~137 days, with seven transits identified in Quarters 1-11.

The physical and orbital parameters of both the host stars and planet were obtained via a photometric-dynamical model, simultaneously fitting both the measured radial velocities and the Kepler light curve of KIC 4862625. The 6.18+/-0.17R_{Earth}_ planet orbits outside the 20 day orbit of an eclipsing binary consisting of an F dwarf (1.734+/-0.044R_{sun}_, 1.528+/-0.087M_{sun}_) and M dwarf (0.378+/-0.023R_{sun}_, 0.408+/-0.024M_{sun}_).
