The detection and characterization of extra-solar planets using the photometric transit method is often made difficult by the existence of stellar activity. Spots, and other stellar photospheric features, are able to induce photometric variations on a star that have difference timescales. Furthermore, these stellar surface inhomogeneities make the transit signal "noisy". In this project we propose that the student will develop a code to simulate transit signals in the presence of active stellar features. The code will then be used to model read data to derive improved parameters for transiting planets.
