The dependence of the gradients of oxygen and nitrogen-to-oxygen on stellar age in MaNGA galaxies

I. A. Zinchenko, J. M. Vilchez, E. Perez-Montero +3

We derive the oxygen abundance (O/H), the nitrogen-to-oxygen (N/O) abundance ratio, and their corresponding radial gradients for a sample of 1431 galaxies from MaNGA DR15 survey us…
