Carbon and nitrogen as indicators of stellar evolution and age. A homogeneous sample of 44 open clusters from the Gaia-ESO Survey
G. Tautvaišienė, A. Drazdauskas, Š. Mikolaitis +11
Context. Low- and intermediate-mass giants undergo a complex chemical evolution that has yet to be observationally probed. The influence of core helium flash on the chemical compos…
Ariel stellar characterisation II. Chemical abundances of carbon, nitrogen, and oxygen for 181 planet-host FGK dwarf stars
R. da Silva, C. Danielski, E. Delgado Mena +12
One of the ultimate goals of the ESA Ariel space mission is to shed light on the formation pathways and evolution of planetary systems in the Solar neighbourhood. Such an endeavour…
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…
Asteroseismology of the multiple stellar populations in the Globular Cluster M4
M. Tailo, E. Corsaro, A. Miglio +6
We present a new asteroseismic analysis of the stars in the Globular Cluster (GC) M4 based on the data collected by the K2 mission. We report the detection of solar-like oscillatio…
Ariel stellar characterisation: I -- homogeneous stellar parameters of 187 FGK planet host stars Description and validation of the method
L. Magrini, C. Danielski, D. Bossini +16
In 2020 the European Space Agency selected Ariel as the next mission to join the space fleet of observatories to study planets outside our Solar System. Ariel will be devoted to th…
The Gaia-ESO Survey: Chemical tagging in the thin disk. Open clusters blindly recovered in the elemental abundance space
L. Spina, L. Magrini, G. G. Sacco +14
The chemical makeup of a star provides the fossil information of the environment where it formed. Under this premise, it should be possible to use chemical abundances to tag stars…
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: 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…
Stellar Population Astrophysics (SPA) with TNG. The old open clusters Collinder 350, Gulliver 51, NGC 7044, and Ruprecht 171
G. Casali, L. Magrini, A. Frasca +9
In the framework of the Stellar Population Astrophysics (SPA) project, we present new observations and spectral analysis of four sparsely studied open clusters, namely Collinder 35…
How magnetic activity alters what we learn from stellar spectra
Lorenzo Spina, Thomas Nordlander, Andrew R. Casey +8
Magnetic fields and stellar spots can alter the equivalent widths of absorption lines in stellar spectra, varying during the activity cycle. This also influences the information th…
Stellar population astrophysics (SPA) with the TNG. Revisiting the metallicity of Praesepe (M44)
Valentina D'Orazi, Ernesto Oliva, Angela Bragaglia +8
Open clusters exquisitely track the Galactic disc chemical properties and its time evolution; a substantial number of studies and large spectroscopic surveys focus mostly on the ch…
Stellar population astrophysics (SPA) with the TNG. Characterization of the young open cluster ASCC 123
A. Frasca, J. Alonso-Santiago, G. Catanzaro +10
Star clusters are key to understand the stellar and Galactic evolution. ASCC 123 is a little-studied, nearby and very sparse open cluster. We performed the first high-resolution sp…
Investigating the population of Galactic star formation regions and star clusters within a Wide-Fast-Deep Coverage of the Galactic Plane
L. Prisinzano, L. Magrini, F. Damiani +32
One of the aims of LSST is to perform a systematic survey of star clusters and star forming regions (SFRs) in our Galaxy. In particular, the observations obtained with LSST will ma…
