Title: Detecting Transiting Southern Sky Exoplanets Around Bright Host Stars

Abstract: We propose to use the CTIO 0.9m telescope to conduct a photometric survey of transit signatures for 7 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 bright host stars (e.g., HD 209458b), such as our targets. The proposed 7 targets orbit stars with V-magnitudes ranging from 7.2-9.4, where all predicted transit windows fall within July 14- 27. TERMS produces the most accurate transit ephemerides available by combining literature and new radial velocity data, which is necessary for detecting transits and characterizing the planetary system. In the event of a transit, we are able to measure the true mass, radius, and density of the planet. Given that many of our targets are long-period (> 10 days), we will also better understand the formation of these planets with respect to known hot Jupiters. In the case of a null detection, our photometry can better constraint the properties of the host star in order to help characterize the exoplanet parameters.
