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…
Investigating Phosphorus Abundances in a Sample of APOGEE-2 Bulge Globular Clusters
Beatriz Barbuy, José G. Fernández-Trincado, Morgan S. Camargo +9
Phosphorus enhanced (P-rich; [P/Fe] > 0.8) giants have been found among mildly metal-poor fiels stars, but in only one star in a globular cluster (GC), M4 (NGC 6121). Also, in a sa…
Abundances of P, S, and K in 58 bulge spheroid stars from APOGEE
B. Barbuy, H. Ernandes, A. C. S. Friaça +25
We have previously studied several elements in 58 selected bulge spheroid stars, based on spectral lines in the H-band. We now derive the abundances of the less-studied elements ph…
Abundances of iron-peak elements in 58 bulge spheroid stars from APOGEE
B. Barbuy, A. C. S. Friaça, H. Ernandes +22
Stars presently identified in the bulge spheroid are probably very old, and their abundances can be interpreted as due to the fast chemical enrichment of the early Galactic bulge.…
Abundances in eight bulge stars from the optical and near-infrared
Patrícia da Silva, B. Barbuy, H. Ernandes +3
Context: The abundances of the -elements are key for understanding the early chemical enrichment of the Galactic bulge. The elements of interest present lines in different wavel…
Abundance analysis of APOGEE spectra for 58 metal-poor stars from the bulge spheroid
R. Razera, B. Barbuy, T. C. Moura +19
The central part of the Galaxy host a multitude of stellar populations, including the spheroidal bulge stars, stars moved to the bulge through secular evolution of the bar, inner h…
