Scientific paper

We analyze nine metal-rich local dwarfs from the sample of Grenon (1990), using high-resolution spectroscopy. Most stars in the sample are very old and should show abundance excess for elements like Ca, Ti, Mg and Si. While these stars are in the Solar neighborhood, their high eccentricity orbits are consistent with an inner disk or bulge origin, and these stars may show the Mg and Ti enhancement consistent with that of the bulge giants. Results of metallicities, alpha -element and r-process element abundances will be presented calculated from equivalent width and spectral synthesis analysis.
