Stellar masses and ages in Gaia Data Release 4 from the Final Luminosity Age Mass Estimator algorithm
Orlagh L. Creevey, Laia Casamiquela, Yveline Lebreton +23
The masses and ages of stars are key quantities for understanding exoplanetary, stellar, and galactic evolution. In the context of Gaia, these parameters provide insights into the…
Gaia FGK benchmark stars: Abundances of n-capture elements of the third version
S. Vitali, P. Jofré, L. Casamiquela +10
In the current era, in which an unprecedented wealth of data are available for the study of the Milky Way, Gaia benchmark stars (GBSs) have become an established reference and cali…
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…
Magnetic Activity Cycles and Rotation in Planet-hosting and Non-hosting Solar-type Stars
Amina Boulkaboul, Alessandro Sozzetti, Caroline Soubiran +1
We analyze periodicities in radial velocity (RV) measurements and magnetic activity indicators (S-index and BIS) for 767 Gaia RV standard stars to distinguish between stellar activ…
Missing pairs in open cluster catalogs
Qingshun Hu, Yufei Cai, Caroline Soubiran +4
Open clusters (OCs) in our Galaxy can be found in pairs, possibly forming physical binaries, or in groups. These objects offer unique insights into the process of star formation an…
Gaia DR3 high radial velocity stars: Genuine fast-moving objects or outliers?
D. Katz, A. Gómez, E. Caffau +39
The third Gaia data release includes 33.8 million radial velocity measurements, extending to a magnitude of G_RVS = 14. To reach this magnitude limit, spectra were processed down t…
