A Hot Saturn Planet Orbiting HD 88133, from the N2K Consortium
  The N2K consortium is carrying out a distributed observing campaign with the Keck, Magellan and Subaru telescopes, as well as the automatic photometric telescopes of Fairborn Observatory, in order to search for short-period gas giant planets around metal-rich stars. We have established a reservoir of more than 14,000 main sequence and subgiant stars, closer than 110 pc, brighter than V=10.5 and with $0.4 < B-V < 1.2$. Because the fraction of stars with planets is a sensitive function of stellar metallicity, a broadband photometric calibration has been developed to identify a subset of 2000 stars with [Fe/H] $> 0.1$ dex for this survey. We outline the strategy and report the detection of a planet orbiting the metal-rich G5IV star HD 88133 with a period of 3.41 days, semi-velocity amplitude, K=35.7 \mse and \msini = 0.29 \mjupe. Photometric observations reveal that HD 88133 is constant on the 3.415-day radial velocity period to a limit of 0.0005 mag. Despite a transit probability of 15.6%, our photometry rules out the shallow transits predicted by the large stellar radius.
