Chemical evolution of the Galactic bulge as traced by microlensed dwarfs and subgiant stars. V. Evidence for a wide age distribution and a complex MDF.
Abstract
For each spectral line we give the lower excitation potential, measured equivalent widths, and derived absolute abundances. We also give median abundances for each star, normalised to the Sun, and errors in the median abundances. These tables contain data for all so far 58 microlensed dwarf stars, and superseeds the tables in Bensby+ (2009, Cat. J/A+A/499/737), Bensby+ (2010, Cat. J/A+A/512/A41), and Bensby+ (2011, Cat. J/A+A/533/A134).
