Breaks in the radial oxygen abundance and corotation radius of three spiral galaxies
(WILEY-BLACKWELL, 2011)
The correlation between the breaks in the metallicity distribution and the corotation radius of spiral galaxies has been already advocated in the past and is predicted by a chemodynamical model of our Galaxy that effectively ...

New quantitative nitrogen abundance estimations in a sample of Seyfert 2 active galactic nuclei
(Wiley Blackwell Publishing, Inc, 2017-06)
We obtained new quantitative determinations of the nitrogen abundance anda consistent relation between nitrogen and oxygen abundances for a sample of Seyfert 2 galaxies located at redshift z < 0.1. We carried out this ...
