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

Abstract: We plan to make use of the high precision velocity measurement ability of the Exoplanet Tracker instrument. We have a new list of bright, metal rich K (plus one M)stars that we plan to add to the 2006B queue observing program at the KPNO 2.1-m telescope. Our stars span the entire RA range available in 2006B and we hope to have E.T. available in two blocks: one near the start of the semester and one near the end. 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. Two-thirds 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.
