cds-question@unistra.frplanetary-nebulaewolf-rayet-starsspectroscopyWe analyse 42 emission-line nuclei of Planetary Nebulae (PNe), in the framework of a large spectrophotometric survey of [WC] nuclei of PNe conducted since 1994, using low/medium resolution spectra obtained at ESO and at OHP. We construct a grid of selected line-intensities (normalized to C IV-5806{AA}=100) ordered by decreasing ionisation potential going from 871 to 24eV. In this grid, the stars appear to belong clearly to prominent O (hot [WO1-4] types) or C (cooler [WC4-11] types) line-sequences, in agreement with the classification of massive WR stars applied to Central Stars of Planetary Nebulae (CSPNe) by Crowther et al. (1998MNRAS.296..367C, CMB98). We propose 20 selected line ratios and the FWHM of CIV and CIII lines as classification diagnostics, which agree well with the 7 line ratios and the FWHM proposed by CMB98.2003A&A...403..659Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/403/659CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/84 : Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (Acker+, 1992)IV/24 : Catalogue of Galactic Planetary Nebulae (Kohoutek, 2001)J/A+A/303/893 : Planetary nebulae with WR-type nuclei (Gorny+, 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/403/659https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/403/659http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/403/659https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/403/659https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/403/659http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/403/659GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/403/659/position (PN positions, from Simbad)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/403/659/position?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/403/659/position?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/403/659/position?GETtext/xml+votable180.050000true268.605417-29.60250.0055555555555555566/1552 2979 3353 3365 3637 3819 4690 6292 11605 12812 12852 12857 12907 12971 13055 13149 14214 14361 14443 14922 15384 15430 15472 16886 20400 21315 23949 24036 28711 28718 28722 28754 28772 28774 28791 28794 28822-28823 28835 28844 28881 28885-28887 28889 28906-28907 28917 28922 28963 28980 28984 29057 29078 29092 29094 29134 29146 29160 29168 29213 29236 29254 29257 29266 29427 29451 29466 29520 29718 29886 30303 30340 30656 30684 30699 31775 31847 37006 37661 37757 37963 37982 38000 38028 38034 38075 38433 39029 39279 39801 40070 41174 41470 41574 41576 41580 41646 41664 41837 41903 41920 42044 42094 42140 42175 42232 42355 42479 42490 42709 42753 42773 42872 44048 47711 47859 47921 48032https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/403/659?format=asciiOpticaldefaultJ/A+A/403/659/positionPN positions, from SimbadrecnoRecord number assigned by the VizieR team.
