Descripción
Aims. We aim to determine the metallicities of 113 Southern Hemisphere Vega-like candidate stars in relation to the giant exoplanet host group and field stars. Methods. We applied two spectroscopic methods of abundance determinations: equivalent width measurements together with the ATLAS9 model atmospheres and the WIDTH9 program, and a comparison of observed spectra with a grid of synthetic spectra. Results. For the Vega-like group, the metallicities are indistinguishable from those of field stars not known to be associated with planets or disks. This result is quite different from the metallicities of giant exoplanet host stars, which are metal-rich in comparison to field stars. © 2008 ESO.
