Title: Confirm and Search for Planet Candidates with the ET Instrument

Abstract: We propose to follow up 10 planet candidates around G and K stars and search 100 more high metallicity G and K stars with V=8-9 using the Exoplanet Tracker (ET) instrument at the KPNO 2.1m telescope. The planet candidates were identified during our first planet survey of a total of 100 solar type stars using the Coude Feed 0.9 meter telescope and ET in Dec. 04 to Mar. 05 and the 2.1 meter in May 2005. One of the candidates appears to be a planet based on the existing radial velocity (RV) and photometry data. We would like to obtain more data to precisely determine its orbital period, mass and eccentricity, and measure the instrument long-term stability. If this planet and other planet candidates are further confirmed by the followup observations, they will represent the first group of planets identified through public telescopes. If the instrument can produce high long term Doppler stability, then ET will be ready for public access starting in fall 2006. High Doppler precision (3-8 m/s) has been demonstrated and rms errors of ~ 10 m/s have been achived for V=8-9 in 10 min exposures using the 2.1 m telescope.
