Abstract
We have traced the Galactic thick disk to its,to date, highest metallicities. Based on high-resolution spectroscopic observations of 187 F and G dwarf stars that kinematically can be associated either with the thin disk (60 stars) or with the thick disk (127 stars), we find that the thick disk stars reach at least solar metallicities, and maybe even higher. This finding is independent of the ULSR, VLSR and WLSR velocities of the stars. 1.
