The presence of a body in an orbit around an eclipsing binary star manifests itself through the light time effect influencing the observed times of eclipses as both the binary and the circumbinary companions move around the common centre of mass. This fact combined with the periodicity with which the eclipses occur can be used to detect the companions.
The main goal of this work is to investigate the potential of the photometry-based eclipse timing of binary stars from the ground as a method of detecting circumbinary planets. We study the usefulness of our Project Solaris, a new network of 0.5-m robotic telescopes, in detecting circumbinary planets.
With the use of the numerical simulations we compare the on-going COROT and Kepler missions with a ground based effort. We study the influence of the white and red photometric noises on the timing precision and provide suggestions for the best targets, observing strategies and instruments for the eclipse timing method.
