Evolution of chemical abundances in Seyfert galaxies
S. K. Ballero, F. Matteucci, L. Ciotti +2
We computed the chemical evolution of spiral bulges hosting Seyfert nuclei, based on updated chemical and spectro-photometrical evolution models for the bulge of our Galaxy, made p…
Chemical evolution of Seyfert galaxies
S. K. Ballero, F. Matteucci, L. Ciotti
We computed the chemical evolution of Seyfert galaxies, residing in spiral bulges, based on an updated model for the Milky Way bulge with updated calculations of the Galactic poten…
The Evolution of Oxygen and Magnesium in the Bulge and Disk of the Milky Way
A. McWilliam, F. Matteucci, S. Ballero +3
We show that the Galactic bulge and disk share a similar, strong, decline in [O/Mg] ratio with [Mg/H]. The similarity of the [O/Mg] trend in these two, markedly different, populati…
Testing the universal stellar IMF on the metallicity distribution in the bulges of the Milky Way and M31
Silvia K. Ballero, Pavel Kroupa, Francesca Matteucci
We test whether the universal initial mass function (UIMF) or the integrated galaxial IMF (IGIMF) can be employed to explain the metallicity distribution (MD) of giants in the Gala…
Formation and evolution of the Galactic bulge: constraints from stellar abundances
Silvia Ballero, Francesca Matteucci, Livia Origlia
We present results for the chemical evolution of the Galactic bulge in the context of an inside-out formation model of the Galaxy. A supernova-driven wind was also included in anal…
The effects of Population III stars and variable IMF on the chemical evolution of the Galaxy
Silvia Kuna Ballero, Francesca Matteucci, Cristina Chiappini
We studied the effects of a hypothetical initial stellar generation (PopIII) of only massive and very massive stars (VMS) on the chemical evolution of the Galaxy. We adopted the tw…
