Title: Detecting Transit Signatures for Southern Sky Exoplanets Around Bright Hosts

Abstract: We propose to use the CTIO 0.9m telescope to conduct a photometric survey of transit signatures for 9 unique exoplanet host stars as part of the Transit Ephemeris Refinement and Monitoring Survey (TERMS). The photometric follow-up of planets discovered by the radial velocity technique has yielded known transiting extra-solar planets, especially for those with the brightest host stars (e.g., HD 209458b), such as our targets. The proposed 9 targets orbit stars with V-magnitudes ranging from 7.2-10.2, where all predicted transit windows fall within Nov 16- 29. TERMS produces the most accurate transit ephemerides available through a combination of literature and new radial velocity data, which is absolutely necessary for observationally detecting transits and characterizing the planetary system. In the event of a transit, we will be able to measure the true mass, radius, and density of the planet. Given that many of our targets are long-period (> 10 days) planets, we will also be able to better understand the formation of these planets with respect to known hot Jupiters. In the case of a null detection, our photometry is used to better constraint the properties of the host star, which can then be used to help characterize the exoplanet parameters.
