However, current methods are limited by many factors, in particular, the biases and physical assumptions that are the basis for the underlying evolutionary or atmospheric models, those that these methods rely upon. Here, we introduce our code spectrAl eneRgy dIstribution bAyesian moDel averagiNg fittEr (ariadne), which tackles this problem by using Bayesian Model Averaging to incorporate the information from all stellar models to arrive at accurate and precise values. This code uses spectral energy distribution fitting methods, combined with precise Gaia distances, to measure the temperature, logg, [Fe/H], A_V_, and radius of a star. When compared with interferometrically measured radii ariadne produces values in excellent agreement across a wide range of stellar parameters, with a mean fractional difference of only 0.001 +/- 0.070. We currently incorporate six different models, and in some cases we find significant offsets between them, reaching differences of up to 550 K and 0.6 R_{sun}_ in temperature and radius, respectively. For example, such offsets in stellar radius would give rise to a difference in planetary radius of 60 per cent, negating homogeneity when combining results from different models. We also find a trend for stars smaller than 0.4-0.5 R_{sun}_, which shows more work needs to be done to better model these stars, even though the overall extent is within the uncertainties of the interferometric measurements. We advocate for the use of ariadne to provide improved bulk parameters of nearby A to M dwarfs for future studies.2022MNRAS.513.2719Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/513/2719CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIV/34 : K2 Ecliptic Plane Input Catalog (EPIC) (Huber+, 2017)IV/38 : TESS Input Catalog - v8.0 (TIC-8) (Stassun+, 2019)IV/39 : TESS Input Catalog version 8.2 (TIC v8.2) (Paegert+, 2021)J/ApJ/831/64 : Mass-metallicity relation for giant planets (Thorngren+, 2016)I/345 : Gaia DR2 (Gaia Collaboration, 2018)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/335 : Revised catalog of GALEX UV sources (GUVcat_AIS GR6+7)V/147 : The SDSS Photometric Catalogue, Release 12 (Alam+, 2015)II/328 : AllWISE Data Release (Cutri+ 2013)https://github.com/jvines/astroARIADNE : ARIADNE algorithm github homehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/513/2719https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/513/2719http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/513/2719https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/513/2719https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/513/2719http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/513/2719GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/513/2719/table3 (Selected stars with stellar properties and their respective references)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/513/2719/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/513/2719/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/513/2719/table3?GETtext/xml+votable180.050000true1.653266729.02150360.0055555555555555566/679 684 1341 2472 2737 3020 3036 3102 3118 3639 3714 3932 3979 4854 5009 5304 5853 6066 6082 6339 7136 7238 7264 7560 8016 8476 8790 8979 8995 9125 9403 9476 9753 9843 10375 10899 11403 11633 11636 11732 11910 12612 12644 12944 12983 13440 14126 14180 14278 14419 14757 14767 14948 15044 15107 15118 15170 15174 15273 15311 15356 15597 15602 16069 17028 17266 17425 17496 17752 18139 18496 18804 19329 19912 20100 20125 20145 20328 21484 22120 22511 22708 22807 23230 23369 23731 23820 24151 24227 24924 26024 26560 26575 26583 26972 26975 27220 28044 28605 28664 28955 28968 29680 30289 30343 30419 30505 30655 30665 30771 30878 30965 31433 31448 32192 32491 32645 33490 36693 36697 36723 40692 41591 42385 44284 45564 45627 45669 46566 490603.830199579824256e-20 1.4134638842407062e-18https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/513/2719?format=asciiUVOpticalInfraredMillimeterdefaultJ/MNRAS/513/2719/table3Selected stars with stellar properties and their respective referencesSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
