Scientific paper

We present the abundances of 18 elements for 10 stars with Jovian-mass planets based on high-resolution, high-S/N spectroscopy obtained with the 9.2-m Hobby-Eberly Telescope (HET) and the 2.2-m MPG/ESO telescope at La Silla observatory. Stellar parameters have been derived spectroscopically and are in good agreement with previous determinations. The abundances are compared to condensation temperatures (Tc) of the elements, and the possible connection between Tc-dependent abundance trends and the presence of planets is discussed.
