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-Díaz, José M. Vílchez +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…

Deriving the abundance distribution of HII galaxies using sulphur as tracer: Exploring the high-metallicity end
Marta Gavilán, Ángeles I. Díaz, Sandra Zamora
The main objective of this work is to derive the distribution of the the metal content of HII galaxies using sulphur as an abundance tracer. This increases the metallicity range th…

Galactic Chemical Evolution: Stellar Yields and the Initial Mass Function
Mercedes Mollá, Oscar Cavichia, Marta Gavilán +1
We present a set of 144 galactic chemical evolution models applied to a Milky Way analogue, computed using four sets of low and intermediate star nucleosynthetic yields, six massiv…
