cds-question@unistra.frdwarf-starsearly-type-starsphotometryeffective-temperatureWe derive an empirical effective temperature and bolometric luminosity calibration for G and K dwarfs, by applying our own implementation of the Infrared Flux Method to multiband photometry. Our study is based on 104 stars for which we have excellent BV(RI)_C_ JHK_s_ photometry, excellent parallaxes and good metallicities. Colours computed from the most recent synthetic libraries (ATLAS9 and MARCS) are found to be in good agreement with the empirical colours in the optical bands, but some discrepancies still remain in the infrared. Synthetic and empirical bolometric corrections also show fair agreement.2006MNRAS.373...13Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/373/13CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/373/13https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/373/13http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/373/13https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/373/13https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/373/13http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/373/13GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/373/13/table1 (Observable and physical quantities for our sample stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/373/13/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/373/13/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/373/13/table1?GETtext/xml+votable180.050000true10.2052940.18717330.0055555555555555566/60 814 1556 2149 2622 3509 3683 5622 5914 6287 6385 6662 8224 8232 8239 8360 9801 10518 11412 12340 12388 12784 13568 14931 15712 16518 16689 17124 17314 17726 18115 18299 18641 19109 19327 20237 20397 20862 21082 22125 22475 22527 23061 23096 23323 23560 25015 25444 25820 25939 26239 26357 26788 26906 27443 27592 27756 28244 28336 30176 30343 30759 30779 30939 31411 31785 32100 33456 33831 33998 34684 35691 35707 35714 35753 35784 36029 36735 37232 37479 38292 38461 39034 39283 40488 41460 41463 41612 41721 42022 42595 43296 43649 44262 44653 44681 44792 44816 46956 46997 47147 48105 487368.650015785639275e-20 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/373/13?format=asciiOpticaldefaultJ/MNRAS/373/13/table1Observable and physical quantities for our sample starsNameName (HD, BD or CD)meta.id;meta.mainchar_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.
