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: Lithium abundances in open cluster Red Clump stars
L. Magrini, R. Smiljanic, E. Franciosini +25
It has recently been suggested that all giant stars with mass below 2 suffer an episode of surface lithium enrichment between the tip of the red giant branch (RGB) and…
The homogeneous characterisation of Ariel host stars
C. Danielski, A. Brucalassi, S. Benatti +20
The Ariel mission will characterise the chemical and thermal properties of the atmospheres of about a thousand exoplanets transiting their host star(s). The observation of such a l…
The Gaia-ESO Survey: A new approach to chemically characterising young open clusters II. Abundances of the neutron-capture elements Cu, Sr, Y, Zr, Ba, La, and Ce
M. Baratella, V. D'Orazi, V. Sheminova +32
Young open clusters (t<200 Myr) have been observed to exhibit several peculiarities in their chemical compositions, from a slightly sub-solar iron content, super-solar abundances o…
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…
The Gaia-ESO survey: Mixing processes in low-mass stars traced by lithium abundance in cluster and field stars
L. Magrini, N. Lagarde, C. Charbonnel +42
We aim to constrain the mixing processes in low-mass stars by investigating the behaviour of the Li surface abundance after the main sequence. We take advantage of the data from th…
Ariel: Enabling planetary science across light-years
Giovanna Tinetti, Paul Eccleston, Carole Haswell +313
Ariel, the Atmospheric Remote-sensing Infrared Exoplanet Large-survey, was adopted as the fourth medium-class mission in ESA's Cosmic Vision programme to be launched in 2029. Durin…
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…
Determination of stellar parameters for Ariel targets: a comparison analysis between different spectroscopic methods
A. Brucalassi, M. Tsantaki, L. Magrini +9
Ariel has been selected as the next ESA M4 science mission and it is expected to be launched in 2028. During its 4-year mission, Ariel will observe the atmospheres of a large and d…
