Gaia FGK Benchmark Stars: Impact of Spectral Resolution on Stellar Abundances
Ivanna Hernández-Araya, Claudia Aguilera-Gómez, Paula Jofré +5
In the era of large Milky Way spectroscopic surveys, calibrating and standardizing stellar parameters and abundance measurements is crucial. The Gaia benchmark stars (GBS) are key…
Stellar nucleosynthesis in the era of large surveys: S-process polluted binaries in GALAH DR4
A. Escorza, S. Vitali, D. Godoy-Rivera +11
Binary interactions during the AGB phase can lead to the formation of chemically peculiar stars with overabundances of s-process elements. Only a few hundreds of these stars have b…
Towards model-free stellar chemical abundances. Potential applications in the search for chemically peculiar stars in large spectroscopic surveys
Theosamuele Signor, Paula Jofré, Hernan Lira +3
Chemical abundance determinations from stellar spectra are challenged by observational noise, limitations in stellar models, and departures from simplifying assumptions. While trad…
Gaia FGK Benchmark Stars: spectral library, metallicities and abundances of and Fe-peak elements of the third version
L. Casamiquela, C. Soubiran, P. Jofré +14
The accurate determination of chemical abundances in stars plays a pivotal role in understanding stellar structure and evolution, nucleosynthesis, and the chemical enrichment histo…
Host-star and exoplanet composition: Polluted white dwarf reveals depletion of moderately refractory elements in planetary material
Claudia Aguilera-Gómez, Laura K. Rogers, Amy Bonsor +6
Planets form from the same cloud of molecular gas and dust as their host stars. Confirming if planetary bodies acquire the same refractory element composition as their natal disc d…
The Gaia-ESO Survey: The DR5 analysis of the medium-resolution GIRAFFE and high-resolution UVES spectra of FGK-type stars
C. C. Worley, R. Smiljanic, L. Magrini +42
The Gaia-ESO Survey is an European Southern Observatory (ESO) public spectroscopic survey that targeted stars in the Milky Way covering the major populations of the disk, bu…
