Four new planets orbiting somewhat metal-enriched stars
  We report the detection of four new extra-solar planets from the Anglo-Australian Planet Search orbiting the somewhat metal-enriched stars HD73526, HD76700, HD30177 and HD2039. The planetary companion of HD 76700 has a circular orbit with a period of 3.98d. With M sin i=0.197+-0.017 Mjup, or 0.69 times the mass of Saturn, is one of the lowest minimum mass extra-solar planets yet detected. The remaining planets all have elliptical orbits with periods ranging from 190.5d to 4.4yr. All four planets have been found orbiting stars from a sub-sample of twenty metal-enriched and faint (V<9) stars, which was added to the Anglo-Australian Planet Search's magnitude-limited V$<$7.5 main sample in October 1998. These stars were selected to be metal-enriched on the basis of their Stromgren photometry, and their enrichment has been subsequently confirmed by detailed spectroscopic analysis.
