Red Giant Stars as Tracers of the Chemical Evolution of the Galactic Bulge (Alan Alves-Brito, PUC-DAA)

The formation and evolution of the Galactic bulge and its relationship with the other Galactic populations is still poorly understood. To establish the chemical differences and/or similarities between the bulge and other stellar populations, we performed a detailed elemental abundance analysis of red giant stars in the bulge and also in the local and inner disks. In this talk, I will discuss our main findings, which suggest that both bulge and thick disk stars experienced similar formation timescales, star formation rates and initial mass functions.
