We used the UVES spectrograph (VLT-UT2 telescope) to obtain high-resolutionspectra of 6 stars hosting transiting planets, namely for OGLE-TR-10, 56, 111,113, 132 and TrES-1. The spectra are now used to derive and discuss thechemical abundances for C, O, Na, Mg, Al, Si, S, Ca, Sc, Ti, V, Cr, Mn, Co, Ni,Cu and Zn. Abundances were derived in LTE, using 1-D plane-parallel Kuruczmodel atmospheres. For S, Zn and Cu we used a spectral synthesis procedure,while for the remaining cases the abundances were derived from measurements ofline-equivalent widths. The resulting abundances are compared with those foundfor stars in the solar neighborhood. Distances and galactic coordinates areestimated for the stars. We conclude that besides being particularlymetal-rich, with small possible exceptions OGLE-TR-10, 56, 111, 113, 132 andTrES-1 are chemically undistinguishable from the field (thin disk) starsregarding their [X/Fe] abundances. This is particularly relevant for the mostdistant of the targets, located at up to ~2 Kpc from the Sun. We also did notfind any correlation between the abundances and the condensation temperature ofthe elements, an evidence that strong accretion of planetary-like material,tentatively connected to planetary migration, did not occur.Comment: Accepted for publication in Astronomy & Astrophysics (June 2006
