cds-question@unistra.frlate-type-starsThe frequency of maximum oscillation power measured in dwarfs and giants exhibiting solar-like pulsations provides a precise, and potentially accurate, inference of the stellar surface gravity. An extensive comparison for about 40 well-studied pulsating stars with gravities derived using classical methods (ionization balance, pressure-sensitive spectral features or location with respect to evolutionary tracks) supports the validity of this technique and reveals an overall remarkable agreement with mean differences not exceeding 0.05dex (although with a dispersion of up to ~0.2dex). It is argued that interpolation in theoretical isochrones may be the most precise way of estimating the gravity by traditional means in nearby dwarfs. Attention is drawn to the usefulness of seismic targets as benchmarks in the context of large-scale surveys.2012MNRAS.419L..34Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/419/L34CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/419/L34https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/419/L34http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/419/L34https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/419/L34https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/419/L34http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/419/L34GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/419/L34/tables1 (Mean effective temperature, iron content and mean surface gravities from the four different methods for the sample stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/419/L34/tables1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/419/L34/tables1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/419/L34/tables1?GETtext/xml+votable180.050000true6.4377931-77.25424610.0055555555555555566/4298 8476 8767 8845 9327 10101 17425 22036 22120 22122 22300 24715 26975 30289 30294 30339 30419 30447 30529 30878 30953 31576 31751 31784 32645 33281 33717 35948 36693 37467 39709 41450 41763 42248 45353 45485 45669 46982https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/419/L34?format=asciiOpticaldefaultJ/MNRAS/419/L34/tables1Mean effective temperature, iron content and mean surface gravities from the four different methods for the sample starsHD?
