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 m s ^ { -1 } and M \sin i~ { } = 0.29 M _ { JUP } .
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 19.5 % , our photometry rules out the shallow transits predicted by the large stellar radius .
