cds-question@unistra.frplanetary-nebulaeinfrared-astronomyspectroscopyWe present the Spitzer/Infrared Spectrograph (IRS) spectra of 157 compact Galactic planetary nebulae (PNe). These young PNe provide insight on the effects of dust in early post-asymptotic giant branch evolution, before much of the dust is altered or destroyed by the hardening stellar radiation field. Most of the selected targets have PN-type IRS spectra, while a few turned out to be misclassified stars. We inspected the group properties of the PN spectra and classified them based on the different dust classes (featureless or F, carbon-rich dust or CRD, oxygen-rich dust or ORD, mixed-chemistry dust or MCD) and subclasses (aromatic and aliphatic, and crystalline and amorphous). All PNe are characterized by dust continuum and more than 80% of the sample shows solid-state features above the continuum, in contrast with the Magellanic Cloud sample where only ~40% of the entire sample displays solid-state features; this is an indication of the strong link between dust properties and metallicity.2012ApJ...753..172Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/753/172CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/298 : AKARI/FIS All-Sky Survey Point Source Catalogues (ISAS/JAXA, 2010)V/127 : MASH Catalogues of Planetary Nebulae (Parker+ 2006-2008)IV/24 : Catalogue of Galactic Planetary Nebulae (Kohoutek, 2001)V/84 : Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (Acker+, 1992)J/A+A/552/A74 : NIR phot. of Galactic PNe with VVV Survey (Weidmann+, 2013)J/A+A/526/A6 : Central stars of galactic planetary nebulae (Weidmann+, 2011)J/ApJ/714/1096 : Galactic planetary nebulae (Stanghellini+, 2010)J/ApJ/689/194 : Distances of galactic planetary nebulae (Stanghellini+, 2008)J/ApJ/671/1669 : Magellanic cloud PNe in the IR (Stanghellini+, 2007)J/MNRAS/357/732 : 2MASS phot. of galactic planetary nebulae (Larios+, 2005)J/A+A/408/1029 : Coordinates of Galactic planetary nebulae (Kerber+, 2003)J/AJ/115/1989 : Distances of galactic planetary nebulae (Tajitsu+, 1998)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/753/172https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/753/172http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/753/172https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/753/172https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/753/172http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/753/172GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/753/172/table1 (Observing log)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/753/172/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/753/172/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/753/172/table1?GETtext/xml+votable180.050000true269.466667-30.13750.0055555555555555565/7217 6/12963 12971 13036 14076 14239 14263 14320 14360 14362 14363 14428 14452 14460 14655 14792 14827 14922 15407 15437 15632 20816 22816 24361 28711 28717 28718 28721 28732 28734 28747 28777 28782 28783 28795 28817 28821 28823 28835 28836 28837 28838 28841 28845 28848 28850 28856 28858 28866 28906 28911 28922 28969 28977 28980 28986 29056 29064 29078 29082 29146 29160 29164 29165 29189 29255 29266 29276 29442 29474 29527 29540 29547 29557 29852 29868 30220 30283 30305 30327 30364 30403 30491 30498 30621 30635 30687 30697 32001 32007 32066 32071 32083 37150 37212 37322 37661 37731 37890 38001 38023 38028 38433 39029 39198 41336 41434 41439 41463 41470 41576 41582 41646 41679 41715 41799 41831 41832 41842 42090 42147 42151 42180 42254 42283 42292 42321 42343 42363 42418 42419 42424 42426 42452 42483 42493 42494 42599 42795 42828 43139 48017 48032https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/753/172?format=asciiInfrareddefaultJ/ApJ/753/172/table1Observing logrecnoRecord number assigned by the VizieR team.
