cds-question@unistra.frwhite-dwarf-starseffective-temperaturex-ray-sourcesultraviolet-astronomyWe present a study of the iron abundance pattern in hot, hydrogen-rich (DA) white dwarfs. The study is based on new and archival far-ultraviolet spectroscopy of a sample of white dwarfs in the temperature range 30000K<=Teff<=64000K. The spectra obtained with the Far Ultraviolet Spectroscopic Explorer, along with spectra obtained with the Hubble Space Telescope Imaging Spectrograph and the International Ultraviolet Explorer, sample FeIII-FeVI absorption lines, enabling a detailed iron abundance analysis over a wider range of effective temperatures than previously afforded.2006ApJ...652.1554Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/652/1554CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/10 : ROSAT All-Sky Bright Source Catalogue (1RXS) (Voges+ 1999)IX/29 : ROSAT All-Sky Survey Faint Source Catalog (Voges+ 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/652/1554https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/652/1554http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/652/1554https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/652/1554https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/652/1554http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/652/1554GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/652/1554/table4 (Soft X-ray to EUV count rate ratios)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/652/1554/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/652/1554/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/652/1554/table4?GETtext/xml+votable180.050000true0.9962543.60.0055555555555555566/7 1283 2078 2734 3204 3566 3693 5025 5176 5871 5898 5902 5936 5941 6040 6070 7212 7631 8155 9433 9506 9651 9962 10194 10386 10969 11514 11621 12083 12088 12111 12698 13133 14263 14654 15169 15287 15391 15914 16046 16052 16158 17415 19970 20423 20716 20760 20940 21416 21885 22051 22069 22749 22846 22870 23101 23644 23789 24591 25138 26678 26851 27322 28026 28243 28259 28389 28982 30406 32781 33576 33639 34197 34454 34515 34676 34822 35573 35626 36739 37096 37427 37808 38325 38804 39464 39689 39825 39880 40356 40466 41068 41283 42454 42760 45782 45909 46180 46700 47002 47011 47180 47459 48516https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/652/1554?format=asciiX-rayUVdefaultJ/ApJ/652/1554/table4Soft X-ray to EUV count rate ratiosrecnoRecord number assigned by the VizieR team.
