Chemical abundances in high-redshift galaxies: a powerful new emission line diagnostic

, 2016
This Letter presents a new, remarkably simple diagnostic specifically designed to derive chemical abundances for high redshift galaxies. It uses only the Hα$\mathrm{H}\alpha$, [N ii] and [S ii] emission lines, which can usually be observed in a single ...

Chemical Abundances of Symbiotic Giants [PDF]

open access: possibleEAS Publications Series, 2015
High resolution (R ∼ 50000), near-IR spectra were used to measure photospheric abundances of CNO and elements around the iron peak for 24 symbiotic giants. Spectrum synthesis was employed using local thermal equilibrium and hydrostatic model atmospheres. The metallicities are distributed in a wide range with maximum around [ Fe / H ] ∼−0.4 – − 0.3 dex.
