cds-question@unistra.frwhite-dwarf-starsmagnetic-fieldsvisible-astronomysloan-photometryFifty-two magnetic white dwarfs have been identified in spectroscopic observations from the Sloan Digital Sky Survey (SDSS) obtained between mid-2002 and the end of 2004, including Data Releases 2 and 3. Although not as numerous or diverse as the discoveries from the first data release, the collection exhibits polar field strengths ranging from 1.5 to ~1000MG and includes two new unusual atomic DQA examples, a molecular DQ, and five stars that show hydrogen in fields above 500MG. The highest field example, SDSS J2346+3853, may be the most strongly magnetic white dwarf yet discovered. Analysis of the photometric data indicates that the magnetic sample spans the same temperature range as for non-magnetic white dwarfs from the SDSS, and support is found for previous claims that magnetic white dwarfs tend to have larger masses than their non-magnetic counterparts. A glaring exception to this trend is the apparently low-gravity object SDSS J0933+1022, which may have a history involving a close binary companion.2005AJ....130..734Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/130/734CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/259 : The SDSS Photometric Catalog, Release 3 (Abazajian+ 2005)http://www.sdss.org : SDSS Home pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/130/734https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/130/734http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/130/734https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/130/734https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/130/734http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/130/734GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/130/734/catalog (New SDSS magnetic white dwarfs (tables 1 and 2 of paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/130/734/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/130/734/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/130/734/catalog?GETtext/xml+votable180.050000true5.370833315.03991670.0055555555555555566/706 4125 4151 4188 4755 4810 4998 5030 5081 5596 5613 5804 5835 6011 6245 6456 7236 9238 9311 9342 9602 9890 9900 10213 10525 10583 10599 10622 10856 10906 10936 10981 11094 11203 11243 11810 13637 17298 18881 19051 19840 21967 26593 27522 27545 27555 27580 27703 27818 27936 27956 367862.040811542443644e-19 6.090060298487514e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/130/734?format=asciiOpticaldefaultJ/AJ/130/734/catalogNew SDSS magnetic white dwarfs (tables 1 and 2 of paper)ComCommentsmeta.notecharrecnoRecord number assigned by the VizieR team.
