We combined Gaia DR3 parallax-based distances with extinction corrected integrated fluxes, and derived luminosities for a sample of 185 stars that had been proposed to be post-AGB stars in the literature. The luminosities allow us to create an HR diagram containing the largest number of post-AGB candidate objects to date. A significant fraction of the objects fall outside the typical luminosity range as covered by theoretical evolutionary post-AGB tracks as well as observed for Planetary Nebula central stars. These include massive evolved supergiants and lower luminosity objects. Here we highlight the fact that one third of the post-AGB candidates is underluminous and we identify these with the recently recognised class of post-Red Giant Branch objects thought to be the result of binary evolution.2022MNRAS.516L..61Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/516/L61CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/469/799 : Torun catalog of post-AGB & related objects (Szczerba+ 2007)J/MNRAS/447/1673 : Galactic post-AGB stars distances (Vickers+, 2015)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/516/L61https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/516/L61http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/516/L61https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/516/L61https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/516/L61http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/516/L61GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/516/L61/post-agb (Post-AGB stars catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/516/L61/post-agb?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/516/L61/post-agb?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/516/L61/post-agb?GETtext/xml+votable180.050000true16.18958379.4463890.0055555555555555566/1229 1813 2495 3080 3262 3353 3649 3780 4018 7064 8490 9412 9436 9713 9733 12300 12813 12970 13046 13210 13283 13729 13917 14040 14248 14256 14323 14339 14355 14357 14367 14390 14400 14425 14436 14440 14443 14450 14453 14559 14566 14598 14602 14611 14641-14642 14738 14893 15410 15486 15588 15612 16709 18436 20623 21090 21543 22069 22085 22392 22425 22450 23013 23471 23695 23707 24079 24317 24649 24813 24848 25501 25751 27858 28676 28681 28719 28724 28751 28772 28774 28801 28804 28822 28840 28849 28857 28864 28867-28868 28885-28886 28889 28900 28936 28994 29087-29088 29129 29164 29189 29200 29202 29207 29254 29257 29261 29270 29278 29303 29335 29394 29529 29545 29579 29646 29776 29870 30127 30215 30223 30297 30310 30314 30340 30428 30452 30506 30562 30682 30687 30796 30915 31018 32036 32081 32093 32117 32458 32537 32543 32562 33299 33506 33807 37211 37245 37337 37501 37890 37892 37908 37912-37913 37925 37965 38021 38027 38433 38812 39188 39223 39233 39365 39405 39774 39918 39935 40492 40555 41093 41382 41433 41463 41566 41593 41622 41663 41670 41676 41691 41701 41707 41709 41759-41760 41769 41784 41826 41837 41879 41897 41920 41945 41967 42044 42149 42156 42168 42171 42213-42214 42227 42233 42254 42310 42314 42349 42370 42387 42419 42433 42436-42437 42443 42454-42455 42495 42561 42608 42841 43013 43029 43047 43064 43085 43107 43130 43155 43174 43227 43235 43559 45373 45725 47016 47717 47867 47921 48488 48537 48822 48879https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/516/L61?format=asciiOpticaldefaultJ/MNRAS/516/L61/post-agbPost-AGB stars catalogueSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
