Chemical evolution of the Milky Way: constraints on the formation of the thick and thin discs
Marco Palla, Francesca Matteucci, Emanuele Spitoni +2
We study the evolution of Milky Way thick and thin discs in the light of the most recent observational data. In particular, we analyze abundance gradients of O, N, Fe and Mg along…
Fluorine in the solar neighborhood: modelling the Galactic thick and thin discs
Valeria Grisoni, Donatella Romano, Emanuele Spitoni +3
We investigate the evolution of the abundance of fluorine in the Milky Way thick and thin discs by means of detailed chemical evolution models compared with recent observational da…
High-precision abundances of elements in solar-type stars. Evidence of two distinct sequences in abundance-age relations
P. E. Nissen, J. Christensen-Dalsgaard, J. R. Mosumgaard +3
HARPS spectra with signal-to-noise ratios S/N > 600 at 6000 A were analysed with MARCS model atmospheres to obtain 1D LTE abundances of C, O, Na, Mg, Al, Si, Ca, Ti, Cr, Fe, Ni, Sr…
On the variation of carbon abundance in galaxies and its implications
Donatella Romano, Mariagrazia Franchini, Valeria Grisoni +3
The trends of chemical abundances and abundance ratios observed in stars of different ages, kinematics, and metallicities bear the imprints of several physical processes that concu…
Detailed abundances in the Galactic center: Evidence of a metal-rich alpha-enhanced stellar population
B. Thorsbro, N. Ryde, R. M. Rich +8
We present a detailed study of the composition of 20 M giants in the Galactic center with 15 of them confirmed to be in the Nuclear Star Cluster. As a control sample we have also o…
Fluorine in the solar neighbourhood: the need for several cosmic sources
Nils Ryde, Henrik Jönsson, Gregory Mace +14
The cosmic origin of fluorine is still not well constrained. Several nucleosynthetic channels at different phases of stellar evolution have been suggested, but these must be constr…
