cds-question@unistra.frwhite-dwarf-starsmultiple-starsproper-motionsinfrared-photometryvisible-astronomybroad-band-photometryThis paper presents results of a near-infrared imaging survey for low-mass stellar and substellar companions to white dwarfs. A wide-field proper-motion survey of 261 white dwarfs was capable of directly detecting companions at orbital separations between 100 and 5000 AU with masses as low as 0.05M_{sun}_, while a deep near-field search of 86 white dwarfs was capable of directly detecting companions at separations between 50 and 1100AU with masses as low as 0.02M_{sun}_. Additionally, all white dwarf targets were examined for near-infrared excess emission, a technique capable of detecting companions at arbitrarily close separations down to masses of 0.05M_{sun}_.2005ApJS..161..394Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/161/394CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/235 : Spectroscopically Identified White Dwarfs (McCook+, 2003)III/70 : Luyten's White Dwarf Catalogues (Luyten, 1970-77)J/ApJS/133/413 : BVRIJHK photometry of cool white dwarfs (Bergeron+, 2001)J/ApJS/156/47 : DA white dwarfs from the Palomar Green Survey (Liebert+ 2005)J/A+A/378/556 : UVES/VLT spectra of white dwarfs (Koester+, 2001)J/AJ/126/1023 : White Dwarfs in the SDSS (Harris+, 2003)J/ApJ/571/512 : Distances of white dwarf stars (Holberg+, 2002)J/ApJ/586/1356 : JHKs photometry of 2MASS white dwarf (Wachter+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/161/394https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/161/394http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/161/394https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/161/394https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/161/394http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/161/394GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/161/394/table1 (Observed targets)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/161/394/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/161/394/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/161/394/table1?GETtext/xml+votable180.050000true0.8817792-16.73288890.0055555555555555566/7 60 64 108 326 333 419 469 473 558 569 696 1082 1248 1307 1381 1434 1449 1554 1746 1916 2157 2182 2364 2497 2536 2625 2808 2816 2912 3129 3213 3252 3552 3819 3983 4067 4199 4312 4344 4375 4450 4455 4473 4481 4566 4570 4606 4910 4947 5025 5065 5082 5091 5097 5190 5195 5356 5410 5423 5429 5608 5636 5816 5827 5902 5927 6118 6452 6458 6477 6523 6547 6579 6705 6737 6808 6867 6923 6935 7036 7252 7257 7265 7267 7270 7361 7428 7478 7483 7498 7559 7631 7663 7672 7686 7756 7902 7958 8199 8361 8442 8475 8510 8546 8559 8894 8915 8965 9071 9072 9305 9336 9349 9424 9433 9458 9463 9484 9602 9610 9651 9747 9840 9985 10131 10173 10378 10445 10474 10504 10525 10589 10599 10637 10647 10905 10935 10936 10968 10969 11020 11027 11094 11131 11159 11176 11193 11217 11346 11416 11511 11550 11593 11642 11645 11662 11784 11973 11984 12022 12111 12157 12206 12268 12541 12738 12746 12747 12791 12901 13013 13065 13085 13103 13249 13263 13295 13652 13668 13923 14149 14391 14400 14533 14559 14586 14667 14832 14865 14923 14991 15280 15335 15411 15462 15538 15687 15738 15944 16078 16158 16245 16433 16440 16451 16501 16551 16599 16672 16697 16744 16777 16785 16799 16895 17007 17089 17094 17158 17415 17463 17595 17685 17879 17943 18068 18079 18086 18133 18139 18246 18334 18341 18368 18415 18511 18556 18557 18700 18709 18875 18902 18911 18950 19042 19122 19141 19183 19364 19434 19522 19629 19875 19970 19975 19999 20098 20155 20198 20203 20210 20287 20360 20369 20404 22638 23090 23101 23105 23174 23407 23468 23476 23495 23497 23507 23544 23545 23644 23789 23924 23947 24409 24491 24795 25073 25084 25460 25634 25712 25792 25942 26027 26168 26172 26282 26321 26326 26386 26471 26495 26678 26740 26851 26911 26916 26929 27019 27078 27218 27221 27338 27350 27385 27395 27504 27536 27594 27595 27631 27902 28026 28092 28110 28183 28212 28257 28259 28271 28488 28523 28559 28574 28982 29413 29522 29855 30093 30251 30415 30440 30506 30617 30621 30754 30855 31179 31282 31290 31528 31637 31670 31677 31690 31702 31708 31710 31714 31735 32385 32423 32436 32462 32608 35490 35573 35626 35713 35769 35817 35826 36125 36315 36567 36858 37174 40682 40944 42760 42984 44291 44898 44953 44996 47002 47957 48516 48699 48728 487817.952274030004205e-20 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/161/394?format=asciiOpticalInfrareddefaultJ/ApJS/161/394/refsReferencesrecnoRecord number assigned by the VizieR team.
