Modelling the chemical evolution of the Galaxy halo
G. Brusadin, F. Matteucci, D. Romano
We study the chemical evolution and formation of the Galactic halo through the analysis of its stellar metallicity distribution function and some key elemental abundance patterns.…
The Galactic Lithium Evolution Revisited
D. Romano, F. Matteucci, P. Molaro +1
The evolution of the 7Li abundance in the Galaxy has been computed by taking into account several 7Li sources: novae, massive AGB stars, C-stars, Type II SNe and GCRs. The theoreti…
Feedback from massive stars and gas expulsion from proto-Globular Clusters
F. Calura, C. G. Few, D. Romano +1
Globular clusters are considerably more complex structures than previously thought, harbouring at least two stellar generations which present clearly distinct chemical abundances.…
Chemical abundances in the nucleus of the Sagittarius dwarf spheroidal galaxy
A. Mucciarelli, M. Bellazzini, R. Ibata +3
We present Iron, Magnesium, Calcium, and Titanium abundances for 235 stars in the central region of the Sagittarius dwarf spheroidal galaxy (within 9.0 arcmin ~70 pc from the cente…
The Gaia-ESO Survey: radial distribution of abundances in the Galactic disc from open clusters and young field stars
L. Magrini, S. Randich, G. Kordopatis +44
The spatial distribution of elemental abundances in the disc of our Galaxy gives insights both on its assembly process and subsequent evolution, and on the stellar nucleogenesis of…
The interplay between super-metallicity, lithium depletion, and radial migration in nearby stars
M. L. L. Dantas, R. Smiljanic, R. Boesso +4
We report the discovery of a peculiar set of old super-metal-rich dwarf stars with orbits of low eccentricity that reach a maximum height from the Galactic plane between 0.5…
