cds-question@unistra.frplanetary-nebulaestellar-distancehertzsprung-russell-diagramWe have compiled a catalogue of central stars of planetary nebulae (CSPN) with reliable distances and positions obtained from Gaia Data Release 2 (DR2) astrometry. Distances derived from parallaxes allow us to analyse the galactic distribution and estimate other parameters such as sizes, kinematical ages, bolometric magnitudes, and luminosities. Our objective is to analyse the information regarding distances together with other available literature data about photometric properties, nebular kinematics, and stellar effective temperatures to throw new light on this rapid and rather unknown evolutionary phase. We seek to understand how Gaia distances compare with other indirect methods commonly used and, in particular, with those derived from non-local thermodynamic equilibrium (non-LTE) models; how many planetary nebulae (PNe) populate the Galaxy; and how are they spatially distributed. We also aim to comprehend their intrinsic luminosities, range of physical sizes of the nebulae; how to derive the values for their kinematical ages; and whether those ages are compatible with those derived from evolutionary models. We considered all PNe listed in catalogues from different authors and in Hong Kong/AAO/Strasbourg/H{alpha} (HASH) database. By X-matching their positions with Gaia DR2 astrometry we were able to identify 1571 objects in Gaia second archive, for which we assumed distances calculated upon a Bayesian statistical approach. From those objects, we selected a sample of PNe with good quality parallax measurements and distance derivations, we which refer to as our Golden Astrometry PNe sample (GAPN), and obtained literature values of their apparent sizes, radial and expansion velocities, visual magnitudes, interstellar reddening, and effective temperatures. We found that the distances derived from DR2 parallaxes compare well with previous astrometric derivations of the United States Naval Observatory and Hubble Space Telescope, but that distances inferred from non-LTE model fitting are overestimated and need to be carefully reviewed. From literature apparent sizes, we calculated the physical radii for a subsample of nebulae that we used to derive the so-called kinematical ages, taking into account literature expansion velocities. Luminosities calculated with DR2 distances were combined with literature central stars Teff values in a Hertzsprung-Russell (HR) diagram to infer information on the evolutionary status of the nebulae. We compared their positions with updated evolutionary tracks finding a rather consistent picture. Stars with the smallest associated nebular radii are located in the flat luminosity region of the HR diagram, while those with the largest radii correspond to objects in a later stage, getting dimmer on their way to become a white dwarf. Finally, we commented on the completeness of our catalogue and calculated an approximate value for the total number of PNe in the Galaxy.2019A&A...630A.150Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/630/A150CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/630/A150https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/630/A150http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/630/A150https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/630/A150https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/630/A150http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/630/A150GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/630/A150/table2 (Astrometric data for 211 planetary nebulae (updated version, 21-Sep-2020))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/630/A150/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/630/A150/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/630/A150/table2?GETtext/xml+votable180.050000true264.9135542-27.78987780.0055555555555555566/1200 1587 1718 1778 1805 1905 3291 3308 3324-3325 3365 3618 3637 3803 3819 4244 4370 4690 5591 5996 6146 6292 6654 7392 9276 9806 11339 11605 11612 12405 12515 12577 12812 12907 12938 12983 13076 13149 13182 13283 14011 14198 14245 14294 14382 14592 14602 14853 15105 15113 15118 15172 15351 15430 15488 15639 15739 15764 16245 16260 16886 20400 20728 21215 21218 21327 21529 21651 21688 21695 21729 21948 22053 22093 22103 22280 22441 22478 22660 23704 23734 23746 25008 27192 28126 28676 28680 28685 28703 28718 28723 28778 28795 28805 28823 28831 28840 28842 28845 28853-28854 28867 28869 28892 28922 28970 28972 29037 29057-29058 29078 29092 29100 29142 29147 29160 29213 29264 29451 30214 30310 30328 30337 30385 30428 30498 30511 30527 30686 30699 31095 31670 31895 32020 32071 32080 32124 32372 32581 32645 33790 36130 37110 37316 37340-37341 37701 37708 37710 37914-37915 37982 38001 38105 38187 38449 38512 39143 39232 39278 39937 40040 40070 40120 40130 40279 40433 40525 40571 40577 41145 41186 41471 41582 41596 41648 41664 41672 41713 41745 41752 41792 41837 41892 41903 41940 42004 42137 42185 42354 42392 42396 42426 42437 42501 42505 42632 42691 42709 42711 42753 42784 43787 44703 44707 46712 47100 48776 48803https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/630/A150?format=asciidefaultJ/A+A/630/A150/table2Astrometric data for 211 planetary nebulae (updated version, 21-Sep-2020)ONameCommon namemeta.idcharrecnoRecord number assigned by the VizieR team.
