On the effects of the Initial Mass Function on Galactic chemical enrichment
S. Goswami, A. Slemer, P. Marigo +7
There is mounting evidence that the stellar initial mass function (IMF) could extend much beyond the canonical Mi ~100, Msun limit, but the impact of such hypothesis on the chemica…
Fluorine Abundances in Local Stellar Populations
K. E. Brady, C. A. Pilachowski, V. Grisoni +2
We present the first fluorine measurements in 12 normal giants belonging to the Galactic thin and thick disks using spectra obtained with the Phoenix infrared spectrometer on the 2…
An asteroseismic age estimate of the open cluster NGC 6866 using Kepler and Gaia
K. Brogaard, T. Arentoft, A. Miglio +10
Asteroseismology of solar-like oscillations in giant stars allow the derivation of their masses and radii. For members of open clusters this allows an age estimate of the cluster w…
Modelling the chemical evolution of Zr, La, Ce and Eu in the Galactic discs and bulge
V. Grisoni, G. Cescutti, F. Matteucci +3
We study the chemical evolution of Zr, La, Ce and Eu in the Milky Way discs and bulge by means of chemical evolution models compared with recent spectroscopic data. We consider det…
The impact of very massive stars on the chemical evolution of extremely metal-poor galaxies
S. Goswami, L. Silva, A. Bressan +6
In recent observations of extremely metal-poor low-mass starburst galaxies, almost solar Fe/O ratios are reported, despite N/O ratios consistent with the low metallicity. We invest…
Abundance gradients along the Galactic disc from chemical evolution models
V. Grisoni, E. Spitoni, F. Matteucci
In this paper, we study the formation and chemical evolution of the Milky Way disc with particular focus on the abundance patterns ([/Fe] vs. [Fe/H]) at different Galactocentri…
