cds-question@unistra.frplanetary-nebulaestellar-distancevisible-astronomykron-cousins-photometryWe have examined central stars of planetary nebulae and symbiotic stars found in the MACHO Galactic bulge database to look for variability. We found four central stars of planetary nebulae and eight symbiotic stars that show variability. We examine the variability and the nature of these objects in detail, as well as reporting on the objects that we did not find to be variable.2010PASP..122..524Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PASP/122/524CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/247 : Variable Stars in the Large Magellanic Clouds (MACHO, 2001)http://wwwmacho.anu.edu.au/ : MACHO Project Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PASP/122/524https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PASP/122/524http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PASP/122/524https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PASP/122/524https://vizier.iucaa.in/viz-bin/votable?-source=J/PASP/122/524http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PASP/122/524GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PASP/122/524/tables (Planetary nebula central stars and symbiotic stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PASP/122/524/tables?https://vizier.iucaa.in/viz-bin/conesearch/J/PASP/122/524/tables?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PASP/122/524/tables?GETtext/xml+votable180.050000true271.7801625-29.21843060.0055555555555555565/7194-7195 7198 6/28745-28747 28750-28751 28766 28769-28772 28774-28775 28784-28785 28791 28796-28798 28821 28823 28865-28868 28870-28871 28880-28882 28886-28889 28938 29058 29064 29164-291652.762881831355591e-19 3.9105737390043815e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PASP/122/524?format=asciiOpticaldefaultJ/PASP/122/524/tablesPlanetary nebula central stars and symbiotic starsrecnoRecord number assigned by the VizieR team.
