Iron-peak elements Sc, V, Mn, Cu and Zn in Galactic bulge globular clusters
H. Ernandes, B. Barbuy, A. Alves-Brito +3
Globular clusters are tracers of the history of star formation and chemical enrichment in the early Galaxy. Their abundance pattern can help understanding their chemical enrichment…
Looking for imprints of the first stellar generations in metal-poor bulge field stars
C. Siqueira-Mello, C. Chiappini, B. Barbuy +9
Context. Efforts to look for signatures of the first stars have concentrated on metal-poor halo objects. However, the low end of the bulge metallicity distribution has been shown t…
High-resolution abundance analysis of red giants in the metal-poor bulge globular cluster HP~1
B. Barbuy, E. Cantelli, A. Vemado +10
The globular cluster HP~1 is projected at only 3.33 degrees from the Galactic center. Together with its distance, this makes it one of the most central globular clusters in the Mil…
High-resolution abundance analysis of HD 140283
C. Siqueira-Mello, S. M. Andrievsky, B. Barbuy +3
HD 140283 is a reference subgiant that is metal poor and confirmed to be a very old star. The abundances of this type of old star can constrain the nature and nucleosynthesis proce…
