cds-question@unistra.frplanetary-nebulaechemical-abundancesspectroscopyWe present new low-resolution (R~800) optical spectra of 22 Galactic PNe with Spitzer spectra. These data are combined with recent optical spectroscopic data available in the literature to construct representative samples of compact (and presumably young) Galactic disc and bulge PNe with Spitzer spectra. Attending to the nature of the dust features seen in their Spitzer spectra, Galactic disc and bulge PNe are classified according to four major dust types (oxygen chemistry or OC, carbon chemistry or CC, double chemistry or DC, featureless or F) and subtypes (amorphous and crystalline, and aliphatic and aromatic). Nebular gas abundances of He, N, O, Ne, S, Cl, and Ar, as well as plasma parameters (e.g. Ne, Te) are homogeneously derived and we study the median chemical abundances and nebular properties in Galactic disc and bulge PNe depending on their Spitzer dust types and subtypes. A comparison of the derived median abundance patterns with AGB nucleosynthesis predictions show mainly that i) DC PNe, both with amorphous and crystalline silicates, display high-metallicity (solar/supra-solar) and the highest He abundances and N/O ratios, suggesting relatively massive (~3-5M_{sun}_) hot bottom burning AGB stars as progenitors; ii) PNe with O-rich and C-rich unevolved dust (amorphous and aliphatic) seem to evolve from subsolar metallicity (z~0.008) and lower mass (<3M_{sun}_) AGB stars; iii) a few O-rich PNe and a significant fraction of C-rich PNe with more evolved dust (crystalline and aromatic, respectively) display chemical abundances similar to DC PNe, suggesting that they are related objects. A comparison of the derived nebular properties with predictions from models combining the theoretical central star evolution with a simple nebular model is also presented. Finally, a possible link between the Spitzer dust properties, chemical abundances, and evolutionary status is discussed.2014A&A...567A..12Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/567/A12CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/84 : Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (Acker+, 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/567/A12https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/567/A12http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/567/A12https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/567/A12https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/567/A12http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/567/A12GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/567/A12/table2 (Observed line fluxes and dereddened intensities (on the scale H{beta}=100))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/567/A12/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/567/A12/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/567/A12/table2?GETtext/xml+votable180.050000true343.7787556.70852780.005555555555555556Cone search capability for table J/A+A/567/A12/table3 (Plasma diagnostics and abundances of Galactic planetary nebulae with Spitzer spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/567/A12/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/567/A12/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/567/A12/table3?GETtext/xml+votable180.050000true86.70837524.36744440.0055555555555555565/7217 6/12971 14076 14239 14363 14452 14460 14792 15437 20816 22816 24361 28711 28716 28718 28722 28726 28732-28734 28746 28754 28777 28782-28783 28805 28820-28822 28837-28838 28843 28845 28847 28850 28856 28858 28860 28865-28866 28872 28881 28886 28889 28898 28906-28907 28911 28917 28922-28923 28977 28980 29056 29064 29078 29104 29146 29164-29165 29168 29189 29201 29206 29255 29266 29276 29286 29297 29442 29451 29474 29520 29527 29540 29852 29870 30283 30491 30498 30635 32071 32083 37151 37212 37322 37661 37731 37890 38000 38023 38028 39029 39198 41336 41439 41470 41576 41582 41646 41679 41799 41831-41832 42090 42180 42283 42312 42321 42343 42418 42425 42452 42479 42483 42493-42494 42599 42795 43139 47859https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/567/A12?format=asciiOpticaldefaultJ/A+A/567/A12/table2Observed line fluxes and dereddened intensities (on the scale H{beta}=100)n_F5876Note on HeI 587.6nm line (2)meta.notecharrecnoRecord number assigned by the VizieR team.
