Title: The Search Continues for Extra-Solar Planets in a Sample of Metal Rich K stars

Abstract: We plan continue our exo-planet search program started in 2006B. We will once again make use of the high precision velocity measurement ability of the Exoplanet Tracker instrument. We have a list of bright, metal rich K (plus one M) stars, some of which have been initially observed in 2006B (data just started at the time of this proposal). The precision available from E.T. and our relatively low mass solar-type stars will allow exo-planets as small in mass as Neptune or less to be discovered. Most of our sample stars all have [Fe/H] > 0.12 making them excellent candidates to harbor planets. Based on current statistics, 5-6% of our stars may have at least one extra-solar ``Jupiter"-like planet and possibly 10-15% (about 4) will have lower mass planets - Neptune to ``super" Earth-like planets.
