cds-question@unistra.frplanetary-nebulaevisible-astronomytrigonometric-parallaxWe matched the astrometry of central stars (CSs) of spectroscopically confirmed Galactic planetary nebulae (PNe) with DR2 Gaia parallaxes (p), finding 430 targets in common with p>0 and |{sigma}_p_/p|<1. A catalog of PNe whose CSs have DR2 Gaia parallaxes is presented in Table 1. We compared DR2 parallaxes with those in the literature, finding good correlation between the two samples. We used PNe parallaxes to calibrate the Galactic PN distance scale. Restricting the sample to objects with 20% parallax accuracy, we derive the distance scale log(R_pc_)=-(0.226+/-0.0155)xlog(S_H{beta}_)-(3.920+/-0.215), which represents a notable improvement with respect to previous ones. We found that the ionized mass versus optical thickness distance scale for Galactic PNe is not as constrained by the Gaia calibrators, but gives important insight into the nature of the PNe, and is essential to define the domain for our distance scale application. We placed the CSs whose distance has been determined directly by parallax on the HR diagram, and found that their location on the post-asymptotic-giant-branch (AGB) H-burning evolutionary tracks is typical for post-AGB stars.2020ApJ...889...21Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/889/21CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/84 : Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (Acker+, 1992)I/345 : Gaia DR2 (Gaia Collaboration, 2018)J/A+AS/94/399 : Absolute fluxes and distances of PN (Cahn+, 1992)J/ApJS/92/125 : Post-AGB evolution (Vassiliadis+, 1994)J/ApJ/459/606 : Distances of planetary nebulae (Schneider+ 1996)J/A+A/405/627 : Angular dimensions of 312 planetary nebulae (Tylenda+, 2003)J/A+A/408/1029 : Coordinates of Galactic planetary nebulae (Kerber+, 2003)J/ApJ/689/194 : Distances of galactic planetary nebulae (Stanghellini+, 2008)J/A+A/588/A25 : Post-AGB & CSPNe evolutionary models (Miller Bertolami, 2016)J/A+A/616/A10 : 46 open clusters GaiaDR2 HR diag (Gaia Collaboration, 2018)J/A+A/616/L2 : Planetary Nebulae distances in Gaia DR2 (Kimeswenger+, 2018)J/A+A/630/A150 : Astrometric data for 211 GAPN (Gonzalez-Santamaria+, 2019)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/889/21https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/889/21http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/889/21https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/889/21https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/889/21http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/889/21GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/889/21/table1 (Catalog of DR2 parallaxes, derived parallax distances and ancillary parameters for Galactic PNe)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/889/21/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/889/21/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/889/21/table1?GETtext/xml+votable180.050000true263.8979292-27.40180280.0055555555555555566/1200 1223 1351 1399 1552 1587 1718 1778 2558 2883 2979 2997 3128 3152 3291 3324-3325 3332 3353 3365 3618 3637 3659 3732 3803 3819 4244 4370 4610 4690 5996 6146 6292 6654 6857 7090 7134 7392 7906 9276 10049 11605 12222 12515 12577 12812 12857 12907 12938 12944 12972 12981 12983 12994 13039 13076 13149 13676 13796 13955 14011 14198 14214 14226 14245 14338-14339 14367 14382 14415 14428-14429 14443 14450 14482 14491 14592 14608 14646 14654 14719 14792 14853 14872 15118 15172 15351 15377 15379 15407 15472 15488 15621 15639 15721 15739 15752 15764 15842 16243 16886 19741 20400 20728 21215 21218 21327 21527 21651 21818 21948 22053 22093 22228 22279-22280 22362 22441 22478 22660 23389 23658 23663 23704 23734 24862 25008 27192 28126 28679 28711 28717-28718 28721-28722 28726 28730 28734 28754 28756 28766 28770 28778-28779 28781-28783 28798 28805 28817 28821 28823 28834 28840 28844 28847 28849-28851 28857 28864-28865 28867-28870 28872 28881 28885-28889 28906 28908 28941 28980 28986 28991 29056-29057 29062-29063 29078 29092 29100 29104 29130 29147 29160 29164-29165 29182 29200 29202 29213 29219 29236 29266 29274 29309 29427 29443 29470 29520 29527 29537 29557 29563 29613 29654 29868 29899 29937 30110 30135 30214 30226 30258 30266 30276 30283 30288 30319 30327 30349 30379 30385 30504 30511 30518 30527 30637 30684 30686 31026 31095 31670 31847 31895 32007 32020 32042 32044 32066 32070-32071 32078 32080 32124 32645 33029 33790 34207 36130 36938 37006 37110 37245 37277 37316 37324 37337 37341 37348 37701 37708 37710 37731 37735 37895 37913 37915 37918 37930 37963 38001-38002 38031 38034 38063 38075 38105 38187 38449 38475 38512 38563 38763 39143 39198-39199 39232 39259 39283 39717 39801 39860 40070 40120 40130 40279 40433 40510 40525 40571 40577 41145 41174 41177 41186 41371 41470 41576 41580 41582 41596 41623 41640 41656 41663-41664 41674 41713 41715 41768 41793 41831-41832 41837 41874 41892 41903 41946 42074 42088 42094-42095 42098-42099 42142 42151-42152 42160 42162 42168 42185 42192 42267 42290 42292 42306 42312 42321 42354 42363 42389 42392 42396 42425-42427 42437 42452 42454 42479 42494 42505 42511-42512 42521 42599 42621 42632 42691 42709 42711 42779 42828 42835 42872 42893 43012 43021 43039 43078 43087 43139 43268 43296 43579 43648 43787 44703 44707 45243 47100 47466 47618 47663 47711 47785 47793 47799 47871 47991 48776 48803 48951 49083https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/889/21?format=asciiOpticaldefaultJ/ApJ/889/21/table1Catalog of DR2 parallaxes, derived parallax distances and ancillary parameters for Galactic PNerecnoRecord number assigned by the VizieR team.
