Publikováno v: The Astronomical Journal, Vol 167, Iss 6, p 291 (2024)

We present the first fluorine measurements in 12 normal K giants belonging to the Galactic thin and thick disks using spectra obtained with the Phoenix infrared spectrometer on the 2.1 m telescope at Kitt Peak. Abundances are determined from the (1�

Autor: E. Spitoni, Fiorenzo Vincenzo, V. Grisoni, Marco Palla, Francesca Matteucci

Publikováno v: Palla, M, Matteucci, F, Spitoni, E, Vincenzo, F & Grisoni, V 2020, ' Chemical evolution of the Milky Way : constraints on the formation of the thick and thin discs ', Monthly Notices of the Royal Astronomical Society, vol. 498, no. 2, pp. 1710-1725 . https://doi.org/10.1093/mnras/staa2437

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 the thin disc as well as the [Mg/Fe] vs. [Fe/H] relations and the meta

The analysis of the APOGEE DR16 data suggests the existence of a clear distinction between two sequences of disc stars at different Galactocentric distances in the [$\alpha$/Fe] vs. [Fe/H] abundance ratio space: the so-called high-$\alpha$ sequence,

Publikováno v: Grisoni, V, Romano, D, Spitoni, E, Matteucci, F, Ryde, N & Jönsson, H 2020, ' Fluorine in the solar neighbourhood: modelling the Galactic thick and thin discs ', Monthly Notices of the Royal Astronomical Society, vol. 498, no. 1, pp. 1252-1258 . https://doi.org/10.1093/mnras/staa2316

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 data. The chemical evolution models adopted here have already been shown
