The Chemical Evolution of Galaxies by Successive Starbursts
T. Contini, R. Coziol, S. Considere +2
We propose an evolutionary scenario by successive bursts of star formation to reproduce the chemical properties of massive nearby Starburst Nucleus Galaxies (SBNGs). The N/O abunda…

The abundance of nitrogen in starburst nucleus galaxies
R. Coziol, R. E. Carlos Reyes, S. Considere +2
We show that the excess of nitrogen emission observed in a large sample of Starburst Nucleus Galaxies (SBNGs) can only be explained at a given metallicity by an overabundance of ni…

Starbursts in barred spiral galaxies. V. Morphological analysis of bars
S. Chapelon, T. Contini, E. Davoust
We have measured the bar lengths and widths of 125 barred galaxies observed with CCDs. The dependence of bar strength (identified with bar axis ratio) on morphological type, nuclea…
