Atmospheric parameters and chemical abundances within 100 pc. A sample of G, K, and M main-sequence stars
Ricardo López-Valdivia, Lucía Adame, Eduardo Zagala Lagunas +9
To date, we have access to enormous inventories of stellar spectra that allow the extraction of atmospheric parameters and chemical abundances essential in stellar studies. However…
Gradients of chemical abundances in the Milky Way from HII regions: distances derived from Gaia EDR3 parallaxes and temperature inhomogeneities
J. E. Méndez-Delgado, A. Amayo, K. Z. Arellano-Córdova +4
We present a reassessment of the radial abundance gradients of He, C, N, O, Ne, S, Cl, and Ar in the Milky Way using the deep optical spectra of 42 HII regions presented in Arellan…
Chemical trends in the Galactic Halo with APOGEE data
E. Fernández-Alvar, L. Carigi, C. Allende Prieto +10
The galaxy formation process in the -Cold Dark Matter scenario can be constrained from the analysis of stars in the Milky Way's halo system. We examine the variation of chemical…
Carbon and oxygen abundances from recombination lines in low-metallicity star-forming galaxies. Implications for chemical evolution
C. Esteban, J. García-Rojas, L. Carigi +4
We present deep echelle spectrophotometry of the brightest emission-line knots of the star-forming galaxies He 2-10, Mkn 1271, NGC 3125, NGC 5408, POX 4, SDSS J1253-0312, Tol 1457-…
HII Regions And the Protosolar Helium, Carbon, and Oxygen Abundances in the Context of Galactic Chemical Evolution
Leticia Carigi, Manuel Peimbert
We present chemical evolution models of the Galactic disk with different Z-dependent yields. We find that a moderate mass loss rate for massive stars of solar metallicity produces…
