  Several investigations of FGK stars in the solar neighborhood have suggested
that thin-disk stars with an iron abundance similar to the Sun appear to show
higher abundances of other elements, such as silicon, titanium, or nickel.
Offsets could arise if the samples contain stars with ages, mean galactocentric
distances, or kinematics, that differ on average from the solar values. They
could also arise due to systematic errors in the abundance determinations, if
the samples contain stars that are different from the Sun regarding their
atmospheric parameters. We re-examine this issue by studying a sample of 80
nearby stars with solar-like colors and luminosities. Among these solar
"analogs", the objects with solar iron abundances exhibit solar abundances of
carbon, silicon, calcium, titanium and nickel.
