cds-question@unistra.frgiant-starseffective-temperatureThe spectral lines of high and low excitation potentials respond differently to the change in effective temperature (Teff). Therefore, the ratio of their depths (or equivalent widths) is a very sensitive temperature indicator. A set of 100 relations is obtained which rely Teff on line depth ratios, calibrated against previously published precise (one per cent) temperature estimates of giants. Highly precise temperatures have been determined from this relations for a set of 110 giants of about solar metallicity, based on high resolution (R=42000), high S/N echelle spectra. The application range of the calibrations is 4000-7000K (F2III-K4III). The internal error of a single calibration is less than 95K, while the combination of all calibrations for a spectrum of S/N=100 reduces uncertainty to only 5-25K (1{sigma}). The big advantage of using line-depth ratios is the independence on the interstellar reddening, spectral resolution, rotational and microturbulence broadening.2006AZh...83...158Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AZh/83/158CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/135 : HD Catalogue and Extension (Cannon+ 1918-1924; ADC 1989)J/A+AS/133/221 : Library of ELODIE spectra (F5-K7 stars) (Soubiran+ 1998)J/A+AS/129/505 : Effective temp. by Infrared Flux Method (Blackwell+ 1998)J/AN/321/277 : Effective temperatures of K-M giants (Strassmeier+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AZh/83/158https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AZh/83/158http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AZh/83/158https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AZh/83/158https://vizier.iucaa.in/viz-bin/votable?-source=J/AZh/83/158http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AZh/83/158GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AZh/83/158/table1 (Teff determinations for 110 giants)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AZh/83/158/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AZh/83/158/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AZh/83/158/table1?GETtext/xml+votable180.050000true4.14183648.24015420.0055555555555555566/210 327 341 377 915 1249 2202 2324 2433 2440 2828 3026 3619 3755 4226 4574 4969 4985 5059 5587 5589 5983 6166 6203 6827 7422 8080 9337 9753 10256 10279 11473 12143 12208 12995 13282 13333 13458 13643 13882 14005 14013 14109 14220 14604 14767 15363 15715 15730 15995 16013 16023 16035 16895 17061 17159 17573 17764 17852 18688 19132 19237 19531 19809 19868 20137 20208 21286 21423 21469 21612 21738 21768 21974 22010 22199 22201 22223 22289 22360 22900 23230 23533 23538 23547 23606 23822 24262 26552 26562 27752 28276 28487 28660 30072 30274 30339 30518 30735 31069 31416 31614 31749 32509 32554 40588 40618 44333 48816 49142https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AZh/83/158?format=asciiOpticaldefaultJ/AZh/83/158/table1Teff determinations for 110 giantsrecnoRecord number assigned by the VizieR team.
