cds-question@unistra.freffective-temperatureoptical-observationcatalogsstellar-radiistellar-massesf-starsLarge spectroscopic surveys devoted to the study of the Milky Way, including Gaia, use automated pipelines to determine the atmospheric parameters of millions of stars. The Gaia FGK benchmark stars are reference stars with Teff and logg derived through fundamental relations, independently of spectroscopy, to be used as anchors for the parameter scale. The first and second versions of the sample have been extensively used for that purpose, and more generally to help constrain stellar models. We provide the third version of the Gaia FGK benchmark stars, an extended set intended to improve the calibration of spectroscopic surveys, and their interconnection. We have compiled about 200 candidates that have precise measurements of angular diameters and parallaxes. We determined their bolometric fluxes by fitting their spectral energy distribution. Masses were determined using two sets of stellar evolution models. In a companion paper, we describe the determination of metallicities and detailed abundances. We provide a new set of 192 Gaia FGK benchmark stars with their fundamental Teff and logg, and with uncertainties lower than 2% for most stars. Compared to the previous versions, the homogeneity and accuracy of the fundamental parameters are significantly improved thanks to the high quality of the Gaia photometric and astrometric data.2024A&A...682A.145Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/682/A145CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/201 : Pulkovo Spectrophotometric Catalog (Alekseeva+, 1997)III/281 : Gaia FGK benchmark stars v2.1 (Jofre+, 2018)J/A+A/564/A133 : Gaia FGK benchmark stars: metallicity (Jofre+, 2014)J/A+A/566/A98 : The Gaia benchmark stars - Library (Blanco-Cuaresma+, 2014)J/A+A/582/A81 : Gaia FGK benchmark stars: abundances (Jofre+, 2015)J/A+A/592/A70 : Gaia FGK stars: low-metallicities candidates (Hawkins+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/682/A145https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/682/A145http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/682/A145https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/682/A145https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/682/A145http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/682/A145GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/682/A145/catalog (Parameters of the stars (corrected version, 04/12/2024, from erratum, 2025A&A...693C...3S))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/682/A145/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/682/A145/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/682/A145/catalog?GETtext/xml+votable180.050000true308.0987-9.85340.0055555555555555566/15 137 428 679 684 998 1341 1410 2691 2837 2921 2923 2997 3036 3102 3118 3619 3639 3712 4146 4376 4438 4559 4574 4854 4990 5009 5304 5382 5535 5670 5853 5982 6066 6219 7238 7264 8476 8767 8834 8845 8986 8995 9083 9127 9216 9327 9476 9717 10084 10375 10899 11394 11403 11633 11732 11910 12056 12704 12944 12953 12960 13301 13332-13333 13440 13550 14084 14239 14278 14419 14744 14757 14948 15044 15107 15118 15170 15174 15176 15273 15320 15356 15567 15597 15895 16035 16069 16115 16192 16689 17262 17425 17496 17568 17582 17723 17752 17854 18139 18688 18893 18907 19323 19585 19912 20145 20278 20308 20328 20390 21182 21469 21477 21484 22015 22120 22300 22708 23096 23140 23190 23201 23230 23283 23369 23540 23753 23820 24151 24715 26302 26457 26552 26575 26952 26975 27198 27220 27568 27857 28605 28664 30228 30339 30419 30529 30665 30878 30965 31416 31433 31576 31784 32192 32561 32645 32754 32994 33281 33377 33874 34051 34169 34263 34730 35025 35118 35185 35382 35415 35532 35602 35673 36035 36433 36693 36697 36723 36803 37507 38072 38216 39026 39340 40618 40692 41763 42081 42248 44284 44542 45564 45668 46176 48519 49060https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/682/A145?format=asciiOpticaldefaultJ/A+A/682/A145/catalogParameters of the stars (corrected version, 04/12/2024, from erratum, 2025A&A...693C...3S)recnoRecord number assigned by the VizieR team.
