cds-question@unistra.frplanetary-nebulaeinfrared-sourcesinfrared-photometryWe have analysed the near-infrared (NIR) and far-infrared (FIR) colours of MASH I and MASH II (the Macquarie/AAO/Strasbourg surveys, Cat. <V/127>) planetary nebulae (PNe), using data deriving from the Two-Micron All-Sky Survey and Infrared Astronomical Satellite. We were able to identify ~5 per cent of the sources in the NIR, and a slightly larger fraction (~12 per cent) in the FIR. It is concluded that whilst the NIR colours of these nebulae are consistent with those of less evolved (and higher surface brightness) PNe, their FIR colours are markedly different. This disparity is likely to arise as a result of an evolution in dust temperatures, in their line emission characteristics, and in the relative contributions of the 8.6 and 11.3um polycyclic aromatic hydrocarbon emission features. A rump of~9 per cent of the detected sources have values log[F(25um)/F(60um)] which are lower than can be explained in terms of normal nebular evolution, however. If these are comparable in nature to the undetected PNe, then this would argue that ~1 in 10 of MASH I and II nebulae may represent galactic H ii regions, Stromgren spheres, symbiotic nebulae or other unrelated categories of source.2009MNRAS.394.1875Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/394/1875CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/127 : MASH Catalogues of Planetary Nebulae (Parker+ 2006-2008)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)II/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/394/1875https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/394/1875http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/394/1875https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/394/1875https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/394/1875http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/394/1875GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/394/1875/table1 (IRAS photometry for MASH I and MASH II sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/394/1875/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/394/1875/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/394/1875/table1?GETtext/xml+votable180.050000true262.5512-26.35030.005555555555555556Cone search capability for table J/MNRAS/394/1875/table2 (2MASS photometry of MASH I and MASH II sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/394/1875/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/394/1875/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/394/1875/table2?GETtext/xml+votable180.050000true268.5785-27.60991670.0055555555555555565/7208 6/21549 21666 22103 28710-28711 28714-28715 28771 28774 28777 28783 28800 28802-28803 28805 28814 28823 28837 28839-28840 28851 28859 28862 28867 28872 28876-28877 28879 28897 28899 28905 28908 28920 29070 29088-29089 29099 29105 29160-29161 29163 29166 29201 29214 29248 29264 29447 29460 29466 29525 29543 29552 29559 30212 30246 30248 30250 30255 30261 30266 30290 30299 30301 30310 30312 30330 30342 30357 30359 30402 37336 37345 37705 37717 37730 37757 37890 37896 37903 37924 37933 37982 38049 39387 39753-39754 39898 39925 41468 41591 41594 41639 41650 41656 41658 41662 41669 41679 41695 41729 41736 41741 41745 41763 41770 41775 41779 41794-41795 41800 41802 41822 41828 41841 41856 41858 41864 41877 42140 42154-42155 42162 42175 42186 42194 42199 42201 42205 42209 42212 42215 42227 42232-42233 42237 42239 42302 42361 42366 42387 42420 42434 42442 42453-42454 42463 42474 42480-42481 42485 42487 42508 42510 42517 42523 42560 42577 43012 43034 430928.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/394/1875?format=asciiInfrareddefaultJ/MNRAS/394/1875/table1IRAS photometry for MASH I and MASH II sourcesrecnoRecord number assigned by the VizieR team.
