Title: Follow-Up Observations of Planet Candidates with the ET Instrument

Abstract: We propose to follow up four planet and two brown dwarf candidates around G and K stars with V=8-9 using the Exoplanet Tracker (ET) instrument at the KPNO 2.1m telescope. These candidates were identified during our earlier planet survey using the Coude Feed 0.9 meter telescope and ET in Dec. 04 to Mar. 05. ET is a new generation high throughput and high Doppler precision instrument developed by the PI's team in 2003-2004. If these candidates are confirmed to be planets, they will represent the first group of planets identified through public telescopes, which will open up a new possibility for general users to access to a state-of-the-art Doppler instrument for planet detection and characterization starting 2006. ET has routinely provided radial velocity (RV) measurements with an rms errors of 15-30 m/s for V=8-9 in 20 min exposures using the Coude feed 0.9 m telescope (Figure 1). We expect to reach 6-13 m/s for V=8-9 with the 2.1m telescope with the same exposure. This high precision will allow us to confirm the planet detection and also precisely determine the orbital parameters of these planets and brown dwarfs.
