Modelling chemical clocks -- Theoretical evidences of the space and time evolution of [s/alpha] in the Galactic disc with Gaia-ESO survey
Marta Molero, Laura Magrini, Marco Palla +6
Chemical clocks based on [s-process elements/alpha-elements] ratios are widely used to estimate ages of Galactic stellar populations. However, the [s/alpha] vs. age relations are n…
The evolution of the Milky Way's thin disc radial metallicity gradient with K2 asteroseismic ages
Emma Willett, Andrea Miglio, J. Ted Mackereth +8
The radial metallicity distribution of the Milky Way's disc is an important observational constraint for models of the formation and evolution of our Galaxy. It informs our underst…
Time evolution of Ce as traced by APOGEE using giant stars observed with the Kepler, TESS and K2 missions
G. Casali, V. Grisoni, A. Miglio +11
Abundances of s-capture process elements in stars with exquisite asteroseismic, spectroscopic, and astrometric constraints offer a novel opportunity to study stellar evolution, nuc…
Spectroscopic age estimates for APOGEE red-giant stars: Precise spatial and kinematic trends with age in the Galactic disc
F. Anders, P. Gispert, B. Ratcliffe +12
Over the last few years, many studies have found an empirical relationship between the abundance of a star and its age. Here we estimate spectroscopic stellar ages for 178 825 red-…
The Gaia-ESO survey: mapping the shape and evolution of the radial abundance gradients with open clusters
L. Magrini, C. Viscasillas Vazquez, L. Spina +27
The spatial distribution of elemental abundances and their time evolution are among the major constraints to disentangle the scenarios of formation and evolution of the Galaxy. We…
Stellar Population Astrophysics (SPA) with the TNG. alpha-elements, lithium, sodium and aluminum in 16 open clusters
R. Zhang, S. Lucatello, A. Bragaglia +13
Exploring the Galactic chemical evolution and enrichment scenarios with open clusters allows us to understand the history of the Milky Way disk. High-resolution spectra of OCs are…
The Gaia-ESO Survey: Age-chemical-clock relations spatially resolved in the Galactic disc
C. Viscasillas Vázquez, L. Magrini, G. Casali +33
The last decade has seen a revolution in our knowledge of the Galaxy thanks to the Gaia and asteroseismic space missions and the ground-based spectroscopic surveys. To complete thi…
Stellar Population Astrophysics (SPA) with the TNG: Stock 2, a little-studied open cluster with an eMSTO
J. Alonso-Santiago, A. Frasca, G. Catanzaro +14
Stock 2 is a little-studied open cluster that shows an extended main-sequence turnoff (eMSTO). In order to investigate this phenomenon and characterise the cluster itself we perfor…
The Gaia-ESO Survey: Galactic evolution of lithium from iDR6
D. Romano, L. Magrini, S. Randich +31
We exploit the unique characteristics of a sample of open clusters (OCs) and field stars for which high-precision 7Li abundances and stellar parameters are homogeneously derived by…
Stellar Population Astrophysics (SPA) with TNG Atmospheric parameters of members of 16 unstudied open clusters
R. Zhang, S. Lucatello, A. Bragaglia +12
Thanks to modern understanding of stellar evolution, we can accurately measure the age of Open Clusters (OCs). Given their position, they are ideal tracers of the Galactic disc. Ga…
Magnetic-buoyancy-induced mixing in AGB Stars: a theoretical explanation of the non-universal [Y/Mg]-age relation
Magrini L., Vescovi D., Casali G. +6
The use of abundance ratios involving Y, or other slow-neutron capture elements, are routinely used to infer stellar ages.Aims.We aim to explain the observed [Y/H] and [Y/Mg] abund…
The Gaia-ESO survey: the non-universality of the age-chemical-clocks-metallicity relations in the Galactic disc
G. Casali, L. Spina, L. Magrini +36
In the era of large spectroscopic surveys, massive databases of high-quality spectra provide tools to outline a new picture of our Galaxy. In this framework, an important piece of…
The Gaia-ESO survey: Calibrating a relationship between Age and the [C/N] abundance ratio with open clusters
G. Casali, L. Magrini, E. Tognelli +51
In the era of large high-resolution spectroscopic surveys, high-quality spectra can contribute to our understanding of the Galactic chemical evolution, providing chemical abundance…
The Gaia-ESO Survey: the N/O abundance ratio in the Milky Way
L. Magrini, F. Vincenzo, S. Randich +31
The abundance ratio N/O is a useful tool to study the interplay of galactic processes, e.g. star formation efficiency, time-scale of infall and outflow loading factor We aim to tra…
