Title: High precision differential photometry of planet transits with the MMTF

Abstract: We propose to use Magellan+MMTF(IMACS) to achieve some of the very highest precision ground-based, time-differential, narrow-band photometry to date on selected favorable transiting planet host stars. The proposed observations are expected to provide precise measurements of the time, duration, shape, and color of an exoplanet transit. Our primary target, CoRoT-7, is an active star hosting the first transiting super-Earth transiting planet, and our color observations will thus be sensitive not just to stellar limb darkening, but also spot activity. We also propose to use the exquisite precision of our tunable filter photometry technique on either GJ 436 or WASP-16, both systems which are in need of additional observations that will contribute towards the detection of small orbital perturbations. This demonstration of the power of tunable filter differential photometry will show how important Magellan+MMTF can be as a resource in the arsenal of ground-based follow- up for Neptune and super-Earth transiting planets yet to be discovered.
