Abstract
The results of a new spectroscopic analysis of HD 75289, recently reported to harbor a Jovian-mass planet, are presented. From high-resolution, high signal-to-noise ratio spectra, we derive [Fe/H] = +0.28 ± 0.05 for this star, in agreement with the spectroscopic study of Gratton et al. published 10 years ago. In addition, we present a reanalysis of the spectra of υ And and τ Boo; our new parameters for these two stars are now in better agreement with photometrically derived values and with the recent spectroscopic analyses of Fuhrmann et al. We also report on extended abundance analyses of 14 Her, HD 187123, HD 210277, and ρ1 Cnc. If we include the recent spectroscopic analyses of HD 217107 by Randich et al. and Sadakane et al., who both reported [Fe/H] ~ +0.30 for this star, we can state that all the hot-Jupiter systems studied to date have metal-rich parent stars. We find that the mean [C/Fe] and [Na/Fe] values among the sample of stars with planets are smaller than the corresponding quantities among field stars of the same [Fe/H].
