A plausible hypothesis is that they are due to the presence of a close stellar or substellar companion. So far, only ~40 binary central stars of PN have been detected, almost all of them with such short periods that their binarity is revealed by photometric variability. Here we have endeavoured to discover binary central stars at any separation, thus determining the unbiased binary fraction of central stars of PN. This number, when compared to the binary fraction of the presumed parent population, can give a first handle on the origin of PN. By detecting the central stars in the I band we have searched for cool companions.2013MNRAS.428.2118Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/428/2118CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/496/813 : Binary PNe towards the Galactic bulge (Miszalski+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/428/2118https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/428/2118http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/428/2118https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/428/2118https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/428/2118http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/428/2118GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/428/2118/table6 (The photometric magnitudes of our targets rounded to three decimal places)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/428/2118/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/428/2118/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/428/2118/table6?GETtext/xml+votable180.050000true75.7813333-15.60633330.005555555555555556Cone search capability for table J/MNRAS/428/2118/table3 (Log of observations taken in photometric conditions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/428/2118/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/428/2118/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/428/2118/table3?GETtext/xml+votable180.050000true6/1587 1718 1778 1905 2997 3618 3803 4244 4370 5037 5996 6654 7090 7134 7392 12515 12983 13814 14245 14382 14719 14853 15764 15842 21218 21818 22280 22441 23746 320202.367228618189496e-19 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/428/2118?format=asciiOpticalInfrareddefaultJ/MNRAS/428/2118/table6The photometric magnitudes of our targets rounded to three decimal placesNamePlanetary nebula namemeta.id;meta.maincharprimarySimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
