Chemical evolution of Na, Mg, and Al in the Galactic bulge from UVES data

R. P. Nunes, B. Barbuy, C. Chiappini +9

The formation of the Galactic bulge remains incompletely understood, with evidence pointing to different stellar populations, including a bar-driven component, an inner-disk popula…

Cobalt and copper abundances in 56 Galactic bulge red giants

H. Ernandes, B. Barbuy, A. Friaça +5

The Milky Way bulge is an important tracer of the early formation and chemical enrichment of the Galaxy. The abundances of different iron-peak elements in field bulge stars can giv…

Oxygen and zinc abundances in 417 Galactic bulge red giants

C. R. da Silveira, B. Barbuy, A. C. S. Friaça +7

Oxygen and zinc in the Galactic bulge are key elements for the understanding of the bulge chemical evolution. Oxygen-to-iron abundance ratios provide a most robust indicator of the…

The GIRAFFE Inner Bulge Survey (GIBS) III. Metallicity distributions and kinematics of 26 Galactic bulge fields

M. Zoccali, S. Vasquez, O. A. Gonzalez +9

Several recent studies have demonstrated that the Galactic bulge hosts two components with different mean metallicities, and possibly different spatial distribution and kinematics.…

Heavy elements Ba, La, Ce, Nd, and Eu in 56 Galactic bulge red giants

M. Van der Swaelmen, B. Barbuy, V. Hill +4

Aims. The aim of this work is the study of abundances of the heavy elements Ba, La, Ce, Nd, and Eu in 56 bulge giants (red giant branch and red clump) with metallicities ranging fr…

Science Case and Requirements for the MOSAIC Concept for a Multi-Object Spectrograph for the European Extremely Large Telescope

C. J. Evans, M. Puech, B. Barbuy +55

Over the past 18 months we have revisited the science requirements for a multi-object spectrograph (MOS) for the European Extremely Large Telescope (E-ELT). These efforts span the…
