Sulphur abundances in star-forming regions from optical emission lines: A new approach based on photoionization models consistent with the direct method
Enrique Pérez-Montero, Borja Pérez-DÃaz, José M. VÃlchez +5
The derivation of sulphur chemical abundances in the gas-phase of star-forming galaxies is explored in this work, using the emission lines produced in these regions in the optical…
