Dwarf Abundances in the Local Region
Earle Luck (Case)
Lithium, carbon, and oxygen abundance data for a sample of nearby dwarfs
(216 stars) including samples within 15 parsecs of the Sun as well as a
sample of local close giant planet (CGP) hosts and comparison stars are
presented. We have re-determined parameters and derived additional
abundances (Z > 10) for the CGP host and comparison samples. From our
abundances for elements with Z > 10 we determine the mean metallicity of
the CGP hosts to be about 0.18 dex higher than non-hosts. However, when
relative abundances ([x/Fe]) are considered we detect no differences in
the samples. This statement is also true for lithium, carbon, and oxygen.
