Here we review the efforts of a number of recent results that use old tracers to understand the build up of the Galaxy. Details that lead directly to using these old tracers to measure distances are discussed. We concentrate on the following: (1) the structure and evolution of the Galactic bulge and inner Galaxy constrained from the dynamics of individual stars residing therein; (2) the spatial structure...
Supersolar oxygen-to-iron ratios are known to exist in nearly all metal-poor stars. But there is no general agreement on the magnitude of these relative overabundances. New high resolution spectra of evolved stars over a large metallicity range have been gathered, from which lines of [O I], Sc II, and Fe II have been measured. Abundance ratios [O/Sc] and [O/Fe], insensitive to most model atmospheric...
