Direct estimates of nitrogen abundance for Seyfert 2 nuclei
O. L. Dors, M. V. Cardaci, G. F. Hägele +10
We derive the nitrogen and oxygen abundances in the Narrow Line Regions (NLRs) of a sample of 38 local () Seyfert~2 nuclei. For that, we consider narrow optical emis…

Chemical abundances of LINER galaxies -- Nitrogen abundance estimations
C. B. Oliveira, A. C. Krabbe, O. L. Dors +5
In this work, we investigated the nitrogen and oxygen abundances in a sample of galaxies with Low Ionization Nuclear Emission Regions (LINERs) in their nucleus. Optical spectroscop…
