The formation of bars and disks in Markarian starburst galaxies
R. Coziol, S. Considere, E. Davoust +1
We have proposed in a companion paper (Considere et al. 2000) that bars appeared recently in massive starburst nucleus galaxies. We now test this hypothesis on an extended sample o…
Starbursts in barred spiral galaxies IV: On young bars and the formation of abundance gradients
S. Considere, R. Coziol, T. Contini +1
The oxygen (O/H) and N/O abundance ratios along the bar of 16 barred spiral starburst galaxies are determined using long-slit spectroscopy. The abundance gradients and the spatial…
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…
The PDS starburst galaxies
R. Coziol, C. A. O. Torres, G. R. Quast +2
(Abridged) We discuss the nature of the galaxies found in the Pico dos Dias Survey (PDS) for young stellar objects. The PDS galaxies were selected from the IRAS Point Source catalo…
