Ariel will be devoted to the characterisation of a thousand planetary atmospheres, for understanding what exoplanets are made of, how they formed and how they evolve. To achieve the last two goals all planets need to be studied within the context of their own host stars, which in turn have to be analysed with the same technique, in a uniform way. We present the spectro- photometric method we have developed to infer the atmospheric parameters of the known host stars in the Tier 1 of the Ariel Reference Sample. Our method is based on an iterative approach, which combines spectral analysis, the determination of the surface gravity from Gaia data, and the determination of stellar masses from isochrone fitting. We validated our approach with the analysis of a control sample, composed by members of three open clusters with well-known ages and metallicities. We measured effective temperature, Teff, surface gravity, logg, and the metallicity, [Fe/H], of 187 F-G-K stars within the Ariel Reference Sample. We presented the general properties of the sample, including their kinematics which allows us to separate them between thin and thick disc populations. A homogeneous determination of the parameters of the host stars is fundamental in the study of the stars themselves and their planetary systems. Our analysis systematically improves agreement with theoretical models and decreases uncertainties in the mass estimate (from 0.21+/-0.30 to 0.10+/-0.02M_{sun}_), providing useful data for the Ariel consortium and the astronomical community at large.2022A&A...663A.161Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/663/A161CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/663/A161https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/663/A161http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/663/A161https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/663/A161https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/663/A161http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/663/A161GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/663/A161/tablea1 (Stellar properties of the 187 stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/663/A161/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/663/A161/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/663/A161/tablea1?GETtext/xml+votable180.050000true291.06369560.74611190.0055555555555555566/437 1066 2308 2584 2596 3876 4145 4268 4624 4720 4730 4990 5170 6181 6539 6638 7036 7240 7649 8197 8237 9459 9524 9653 10407 10654 11455 12342 12424 12644 12853 12862 13143 13439 13680 14772 14886 14931 14993 15029 15129 15218 16405 16432 16633 16947 17162 17172 17226-17227 17819 17851 17865 18093 18147 18452 18473 18490 18510 18569 18766 18786 18880 18943 20116 20339 20565 20648 20682 20780 20790 21026 21176 21254 21876 22001 22505 22519 22816 22963 24205 24409 24752 24815 24858 25132 25153 25194 25427 25433 25604 25723 25794 25885 25950 26019 26062 26771 26844 26918 26992 27056 27488 27780 28400 28433 29002 29012 29022 29349 30013 30157 30295 30466 30485 31541 31641 32217 32749 33157 33220 33719 33723 33798 34370 34471 34566 34708 34847 34898 35210 35993 36142 36165 36196 36667 36794 38233 38452 38682 39007 39487 39611 39812 39829 40014 40194 40320 40862 42001 42865 42936 42986 43336 43432 43541 43586 43625 43775 43847 43865 43960 44431 44648 44672 45766 45855 46316 46421 46429 46437 47000 47167 47186 47476 47681 48005 48076 48117 48121 48165 48178 48338 48727 48747 48803 49103https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/663/A161?format=asciiOpticaldefaultJ/A+A/663/A161/tablea1Stellar properties of the 187 starsSimbadNameSimbad column added by the CDSmeta.idcharnullableIDIdentification of the starmeta.id;meta.maincharf_xi[0/1] Flag on the microturbulent velocity, (0 derived, 1 assumed)meta.codeintSReference for the spectrameta.ref;pos.framechar_RARight Ascension (J2000) from SIMBAD (not part of the original data)degpos.eq.ra;meta.main_DEDeclination (J2000) from SIMBAD (not part of the original data)degpos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
