Abstract

We have analyzed the circumnuclear ring of the spiral galaxy NGC7742 in order to understand its formation and evolution. We have obtained gaseous abundances, characterized the interstellar medium of the clusters and studied the properties of the ionizing clusters. We have also implemented a new methodology using the red wavelength range of optical spectra, with the purpose of understanding how star formation evolves in high metallicity environments.
