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.
