ABSTRACT
We report the results of abundance analyses of new samples of stars with planets and stars without detected planets. We employ these data to compare abundance–condensation temperature trends in both samples. We find that stars with planets have more negative trends. In addition, the more metal-rich stars with planets display the most negative trends. These results confirm and extend the findings of Ramirez et al. and Melendez et al., who restricted their studies to solar analogues. We also show that the differences between the solar photospheric and CI meteoritic abundances correlate with condensation temperature.
