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…
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…
Full abundance study of two newly discovered barium giants
Sara Vitali, Ana Escorza, Ditte Slumstrup +1
Barium (Ba) stars are chemically peculiar stars that show enhanced surface abundances of heavy elements produced by the slow-neutron-capture process, the so-called s-process. These…
Gaia FGK Benchmark Stars: fundamental Teff and log g of the third version
Caroline Soubiran, Orlagh Creevey, Nadege Lagarde +8
Context. Large spectroscopic surveys devoted to the study of the Milky Way, including Gaia, use automated pipelines to massively determine the atmospheric parameters of millions of…
