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…
Ionization correction factors and dust depletion patterns in giant HII regions
A. Amayo, G. Delgado-Inglada, G. Stasinska
We provide new ionization correction factors (ICFs) for carbon, nitrogen, neon, sulfur, chlorine, and argon in giant H II regions. The ICFs were computed using the most representat…
A study of extragalactic planetary nebulae populations based on spectroscopy. I. Data compilation and first findings
Gloria Delgado-Inglada, Jorge García-Rojas, Grazyna Stasińska +1
We compile published spectroscopic data and [O III] magnitudes of almost 500 extragalactic planetary nebulae (PNe) in 13 galaxies of various masses and morphological types. This is…
Ionization correction factors for sodium, potassium, and calcium in planetary nebulae
Alexia Amayo, Gloria Delgado-Inglada, Jorge García-Rojas
We use a large grid of photoionization models that are representative of observed planetary nebulae (PNe) to derive ionization correction factors (ICFs) for sodium, potassium, and…
Ionization correction factors for ionized nebulae
Gloria Delgado-Inglada, Alexia Medina-Amayo, Grażyna Stasińska
In this paper we discuss the calculation of chemical abundances in planetary nebulae and H II regions through ionization correction factors (ICFs). We review the first ICFs propose…
Nebular spectroscopy: A guide on H II regions and planetary nebulae
Manuel Peimbert, Antonio Peimbert, Gloria Delgado-Inglada
We present a tutorial on the determination of the physical conditions and chemical abundances in gaseous nebulae. We also include a brief review of recent results on the study of g…
