Abstract
The abundances of 16 elements (C through Y) in the recently detected planet -harboring G4 IV star HD 38529 are presented. A spectroscopic analysis was carried out differentially relative to the Sun. The adopted atmospheric par ameters of the star are T-eff = 5500 +/- 100 K, log g = 3.6 +/- 0.1, xi (t) = 1.0 +/- 0.3 km s(-1) and [M/H] = +0.3. Iron is definitely overabundant w ith respect to the Sun, [Fe/H] = +0.40 +/- 0.06, and all other elements are also found to be enhanced, The enhancements of iron peak elements (Ti thro ugh Ni) are coincident with that of Fe within +/-0.1 dex, while C and O are slightly less enhanced than Fe.
