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 evolution of the Oxygen abundance radial gradient in the Milky Way Galaxy disk
M. Mollá, O. Cavichia, R. D. D Costa +3
We review the state of our chemical evolution models for spiral and low mass galaxies. We analyze the consequences of using different stellar yields, infall rate laws and star form…
Galactic Chemical Evolution
M. Mollá, O. Cavichia, R. da Costa +2
We analyze the evolution of oxygen abundance radial gradients resulting from our chemical evolution models calculated with different prescriptions for the star formation rate (SFR)…
Properties of the outer regions of spiral disks: abundances, colors and ages
Mercedes Mollá, Angeles I. Díaz, Brad K. Gibson +2
We summarize the results obtained from our suite of chemical evolution models for spiral disks, computed for different total masses and star formation efficiencies. Once the gas, s…
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…
CALIFA, the Calar Alto Legacy Integral Field Area survey: IV. Third Public data release
S. F. Sánchez, R. García-Benito, S. Zibetti +60
This paper describes the Third Public Data Release (DR3) of the Calar Alto Legacy Integral Field Area (CALIFA) survey. Science-grade quality data for 667 galaxies are made public,…
Shape of the oxygen abundance profiles in CALIFA face-on spiral galaxies
L. Sánchez-Menguiano, S. F. Sánchez, I. Pérez +25
We measured the gas abundance profiles in a sample of 122 face-on spiral galaxies observed by the CALIFA survey and included all spaxels whose line emission was consistent with sta…
