cds-question@unistra.frwhite-dwarf-starsinfrared-photometryeffective-temperatureWe present spectra for 33 previously unclassified white dwarf systems brighter than V=17, primarily in the southern hemisphere. Of these new systems, 26 are DA, 4 are DC, 2 are DZ, and 1 is DQ. We suspect that three of these systems are unresolved double degenerates. We obtained VRI photometry for these 33 objects, as well as for 23 known white dwarf systems without trigonometric parallaxes, also primarily in the southern hemisphere. For the 56 objects, we converted the photometry values to fluxes and fit them to a spectral energy distribution using the spectroscopy to determine which model to use (i.e., pure hydrogen, pure helium, or metal-rich helium), resulting in estimates of Teff and distance.2007AJ....134..252Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/134/252CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/129/413 : New high proper motion stars (-90<DE<-47) (Subasavage+, 2005)J/AJ/130/1658 : New high proper motion stars (-47<DE<-00) (Subasavage+, 2005)J/AJ/133/2898 : New proper-motion stars (-90<DE<-47) (Finch+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/134/252https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/134/252http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/134/252https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/134/252https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/134/252http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/134/252GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/134/252/wd (New and known white dwarfs data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/134/252/wd?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/134/252/wd?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/134/252/wd?GETtext/xml+votable180.050000true9.0929583-59.92430560.0055555555555555566/2113 20550 20641 23235 24778 24795 24882 24912 25075 25220 25250 25634 26962 31956 31973 32969 33011 33384 33543 33855 34197 34309 34662 34864 34959 35268 35412 37084 37464 37477 38381 38803 39425 40283 40747 41109 41125 41237 42825 42984 43805 44094 44630 44971 45173 45201 45561 45782 46678 46709 46841 46854 47476 47487 47993 48132https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/134/252?format=asciiInfrareddefaultJ/AJ/134/252/wdNew and known white dwarfs datarecnoRecord number assigned by the VizieR team.
