Giants in the local region

We present parameter and abundance data for a sample of 298 nearby giants. The spectroscopic data for this work have a resolution of R similar to 60; 000, S/ N > 150, and spectral coverage from 475 to 685 nm. Overall trends in the Z > 10 abundances are dominated by Galactic chemical evolution, while the light- element abundances are influenced by stellar evolution, as well as Galactic evolution. We find several super- Li stars in our sample and confirm that Li abundances in the first giant branch are related to mixing depths. Once astration of lithiumon the main sequence along with the overall range of main- sequence lithium abundances are taken into account, the lithium abundances of the giants are not dramatically at odds with the predictions of standard stellar evolution. We find the giants to be carbon-diluted in accord with standard stellar evolution and that the carbon and oxygen abundances determined for the local giants are consistent with those found in local field dwarfs. We find that there is evidence for systematic carbon variations in the red giant clump in the sense that the blue side of the clump is carbon- poor ( more diluted) than the red side.
