The multi-zone chemical evolution of the Galactic bulge: predicting abundances for different radial zones
Oscar Cavichia, Mercedes Mollá, Juanjo J. Bazán
Due to its proximity, the stellar populations of the Galactic bulge (GB) can be resolved and can be studied in detail. This allows tracing the bulge metallicity distribution functi…
Chemical abundances of photoionized nebulae in the Local Group
W. J. Maciel, R. D. D. Costa, O. Cavichia
Photoionized nebulae comprise basically HII regions and planetary nebulae, and their abundances give important clues on the nucleosynthesis and chemical evolution of their host gal…
Improving the determination of chemical abundances in planetary nebulae
O. Cavichia, R. D. D. Costa, W. J. Maciel +1
Planetary nebulae are the products of the evolution of low and intermediate mass stars. The chemical property studies of these objects give important information about the elementa…
The evolution of the radial gradient of Oxygen abundance in spiral galaxies
M. Mollá, A. I. Díaz, Y. Ascasibar +4
The aim of this work is to present our new series of chemical evolution models computed for spiral and low mass galaxies of different total masses and star formation efficiencies.…
The role of gas infall in the evolution of disc galaxies
Mercedes Mollá, Ángeles I. Díaz, Brad K. Gibson +2
Spiral galaxies are thought to acquire their gas through a protracted infall phase resulting in the inside-out growth of their associated discs. For field spirals, this infall occu…
Planetary nebulae in the inner Milky Way: new abundances
O. Cavichia, R. D. D. Costa, W. J. Maciel
The study of planetary nebulae in the inner-disk and bulge gives important information on the chemical abundances of elements such as He, N, O, Ar, Ne, and on the evolution of thes…
