cds-question@unistra.frwhite-dwarf-starseffective-temperaturestellar-massesWe present atmospheric parameters for a large sample of DA white dwarfs that are known to be photometrically constant. For each star, we determine the effective temperature and surface gravity by comparing high signal-to-noise ratio optical spectra to the predictions of detailed model atmosphere calculations. We also report the successful prediction and detection of photometric variability in G232-38 based on similar Teff and logg determinations. The atmospheric parameters derived for this sample of constant stars, as well as those for the known sample of bright ZZ Ceti stars (now boosted to a total of 39), have been obtained in a highly homogeneous way.2005ApJ...631.1100Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/631/1100CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/235 : Spectroscopically Identified White Dwarfs (McCook+, 2006)J/ApJS/156/47 : DA white dwarfs from Palomar Green Survey (Liebert+, 2005)J/MNRAS/335/673 : DA white dwarfs in 2dF QSO Redshift Survey (Vennes+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/631/1100https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/631/1100http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/631/1100https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/631/1100https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/631/1100http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/631/1100GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/631/1100/tables (Atmospheric parameters of DA white dwarfs, photometrically constant and ZZ Ceti stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/631/1100/tables?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/631/1100/tables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/631/1100/tables?GETtext/xml+votable180.050000true1.895-16.09222220.0055555555555555566/108 238 326 333 469 696 863 951 1434 1554 1848 2364 2366 2536 2761 2808 2912 3152 3313 3577 4531 4566 5195 5420 5429 5539 5608 5816 5827 5989 6454 6466 6579 6867 8250 8546 8595 8727 9424 9483 9840 10173 10999 11050 11374 11511 11593 11662 12714 12747 12900 13295 13714 13854 14190 14792 14807 15446 15462 15474 16158 16440 16799 17170 17625 17685 17846 18068 18079 18086 18133 18931 19251 20001 20078 20155 20360 20404 22891 23090 23468 23533 23924 24499 25371 25792 25960 26258 27078 27179 27350 27381 27395 27429 27930 28110 28460 29182 29486 29522 30093 30251 30440 30650 30696 30892 31172 31282 31677 31702 31710 32436 33011 35769 35957 37084 37370 38036 40070 42700 44898 45110 45318 45921 48781https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/631/1100?format=asciidefaultJ/ApJ/631/1100/refsReferencesrecnoRecord number assigned by the VizieR team.
