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…
Mapping the Galactic Metallicity Gradient with Open Clusters: The State-of-the-Art and Future Challenges
Lorenzo Spina, Laura Magrini, Katia Cunha
In this paper, we make use of data collected for open cluster members by high-resolution spectroscopic surveys and programmes (i.e., APOGEE, Gaia-ESO, GALAH, OCCASO, and SPA). Thes…
Chemical evidence for planetary ingestion in a quarter of Sun-like stars
Lorenzo Spina, Parth Sharma, Jorge Meléndez +5
Stellar members of binary systems are formed from the same material, therefore they should be chemically identical. However, recent high-precision studies have unveiled chemical di…
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…
Radial velocity precision of ESPRESSO through the analysis of the solar twin HIP 11915
Yuri Netto, Diego Lorenzo-Oliveira, Jorge Meléndez +4
Different stellar phenomena affect radial velocities (RVs), causing variations large enough to make it difficult to identify planet signals from the stellar variability. RV variati…
