cds-question@unistra.frplanetary-nebulaeinfrared-photometryWe discuss the infrared (IR) (1.25-5microns) photometry of eight planetary nebulae performed in 1999-2006. For all of the nebulae under study, we have firmly established IR brightness and color variations on time scales shorter than one year and up to 6-8 years. The greatest IR brightness variations were observed in IC 2149, IC 4997, and NGC 7662. Their J magnitudes varied within 0.2-0.25mag. In the remaining objects, the J magnitude variations did not exceed 0.15mag. All of the planetary nebulae under study exhibited IR color variations. Based on the IR photometry, we have classified the central regions of planetary nebula NGC 1514 and of the northern part of NGC 7635 seen through a 12" aperture as B(3-7) main-sequence star (NGC 1514) and O9.5 upper-main-sequence star (NGC 7635). The nebulae IC 4997 and NGC 7027 exhibited an excess emission (with respect to the emission from a hot source) at wavelength more than 2.5micron.2007PAZh...33..657Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/PAZh/33/657CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/PAZh/33/657https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/PAZh/33/657http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/PAZh/33/657https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/PAZh/33/657https://vizier.iucaa.in/viz-bin/votable?-source=J/PAZh/33/657http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/PAZh/33/657GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/PAZh/33/657/stars (List of program PNe)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/PAZh/33/657/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/PAZh/33/657/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/PAZh/33/657/stars?GETtext/xml+votable180.050000true62.3207530.77597220.0055555555555555566/1200 1399 6146 12852 13676 13995 14311 15172https://cdsarc.cds.unistra.fr/viz-bin/moc/J/PAZh/33/657?format=asciiInfrareddefaultJ/PAZh/33/657/starsList of program PNerecnoRecord number assigned by the VizieR team.
