Oxygen abundance distributions in six late-type galaxies based on SALT spectra of HII regions
I. A. Zinchenko, A. Y. Kniazev, E. K. Grebel +1
Spectra of 34 H II regions in the late-type galaxies NGC1087, NGC2967, NGC3023, NGC4030, NGC4123, and NGC4517A were observed with the South African Large Telescope (SALT). In all 3…
On the radial abundance gradients in disks of irregular galaxies
L. S. Pilyugin, E. K. Grebel, I. A. Zinchenko
We determine the radial abundance distributions across the disks of fourteen irregular galaxies of the types Sm and Im (morphological T types T = 9 and T =10) as traced by their HI…
On the Influence of Minor Mergers on the Radial Abundance Gradient in Disks of Milky Way-like Galaxies
Igor A. Zinchenko, Peter Berczik, Eva K. Grebel +2
We investigate the influence of stellar migration caused by minor mergers (mass ratio from 1:70 to 1:8) on the radial distribution of chemical abundances in the disks of Milky Way-…
