The outside-in formation of elliptical galaxies
Antonio Pipino, Francesca Matteucci, Cristina Chiappini
In this paper we compare the predictions of a detailed multi-zone chemical evolution model for elliptical galaxies with the very recent observations of the galaxy NGC 4697. As a co…
Photo-chemical evolution of elliptical galaxies II. The impact of merging-induced starbursts
Antonio Pipino, Francesca Matteucci
The effects of late gas accretion episodes and subsequent merger-induced starbursts on the photo-chemical evolution of elliptical galaxies are studied and compared to the picture o…
The chemical evolution of Barium and Europium in the Milky Way
G. Cescutti, P. Francois, F. Matteucci +2
We compute the evolution of the abundances of barium and europium in the Milky Way and we compare our results with the observed abundances from the recent UVES Large Program "First…
The Evolution of Barium and Europium in Local Dwarf Spheroidal Galaxies
Gustavo A. Lanfranchi, Francesca Matteucci, Gabriele Cescutti
By means of a detailed chemical evolution model, we follow the evolution of barium and europium in four Local Group Dwarf Spheroidal Galaxies, in order to set constraints on the nu…
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…
The origin of nitrogen: Implications of recent measurements of N/O in Galactic metal-poor stars
C. Chiappini, F. Matteucci, S. K. Ballero
Recent new high-precision abundance data for Galactic halo stars suggest important primary nitrogen production in very metal-poor massive stars. Here, we compute a new model for th…
