cds-question@unistra.frgiant-starsstellar-distanceWe have commenced a detailed analysis of the known sample of Galactic post-asymptotic giant branch (PAGB) objects compiled in the Torun catalogue of Szczerba et al. (2007A&A...469..799S, Cat. J/A+A/469/799), and present, for the first time, homogeneously derived distance determinations for the 209 likely and 87 possible catalogued PAGB stars from that compilation. Knowing distances are essential in determining meaningful physical characteristics for these sources and this has been difficult to determine for most objects previously. The distances were determined by modelling their spectral energy distributions (SEDs) with multiple blackbody curves, and integrating under the overall fit to determine the total distance-dependent flux. This approach was undertaken for consistency as precise spectral types, needed for more detailed fitting, were unknown in the majority of cases. The SED method works because the luminosity of these central stars is very nearly constant from the tip of the AGB phase to the beginning of the white dwarf cooling track. This then enables us to use a standard-candle luminosity to estimate the SED distances. For Galactic thin-disc PAGB objects, we use three luminosity bins based on typical observational characteristics, ranging between 3500 and 12000L_{sun}_. We further adopt a default luminosity of 4000L_{sun}_ for bulge objects and 1700L_{sun}_ for the thick-disc and halo objects. We have also applied the above technique to a further sample of 54 related nebulae not in the current edition of the Torun catalogue. In a follow-up paper, we will estimate distances to the subset of RV Tauri variables using empirical period-luminosity relations, and to the R CrB stars, allowing a population comparison of these objects with the other subclasses of PAGB stars for the first time.2015MNRAS.447.1673Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/447/1673CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/469/799 : Torun catalog of post-AGB and related objects (Szczerba+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/447/1673https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/447/1673http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/447/1673https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/447/1673https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/447/1673http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/447/1673GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/447/1673/table4 (Derived Parameters and distances for 209 likely PAGB stars in the Torun catalogue, ordered by Galactic longitude (table 4 in the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/447/1673/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/447/1673/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/447/1673/table4?GETtext/xml+votable180.050000true270.3142-29.444110.005555555555555556Cone search capability for table J/MNRAS/447/1673/table5 (Derived Parameters and distances for 87 possible PAGB stars in the Torun catalogue, ordered by Galactic longitude)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/447/1673/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/447/1673/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/447/1673/table5?GETtext/xml+votable180.050000true274.00198-30.756530.005555555555555556Cone search capability for table J/MNRAS/447/1673/table6 (Derived Parameters and distances for 54 miscellaneous objects not in the Torun Catalogue, ordered by Galactic longitude)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/447/1673/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/447/1673/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/447/1673/table6?GETtext/xml+votable180.050000true270.15659-29.363910.0055555555555555566/1229 1238 1813 2495 3080 3262 3353 3649 3780 4018 4361 4365 7064 8490 9412 9436 9713 9733 12300 12813 12970 13046 13210 13283 13297 13729 13917 13995 14005 14040 14248 14256 14279 14323 14339 14355 14357 14367 14390 14400 14425 14436 14440 14443 14450 14453 14487 14559 14566 14598 14602 14611 14641-14642 14672 14694 14736 14738 14808 14893 15410 15486 15588 15612 15624 15663 15699 15718 15741 15762 16709 18436 20623 21090 21326 21523 21543 21888 22037 22069 22085 22392 22425 22450 23013 23471 23695 23707 24079 24317 24649 24813 24848 25501 25751 27858 28676 28681 28705 28719 28724 28733-28734 28746 28751 28772 28774 28801-28802 28804 28812 28822 28825 28840 28845 28849 28857 28863-28864 28867-28868 28876 28885-28886 28889 28900 28908 28919 28936 28994 29087-29088 29095 29103 29129 29161 29164 29170 29189 29200 29202 29207 29254-29255 29257 29261 29267 29270 29277-29278 29303 29335 29394 29451 29460 29506 29529 29545 29571 29579 29646 29776 29870 30127 30215 30223 30229 30263 30269 30271 30297 30303 30310 30313-30314 30322 30330-30331 30340 30428 30452 30506 30562 30615 30621 30678 30682 30687-30688 30717 30796 30803 30915 31018 32036 32081 32093 32117 32458 32537 32543 32562 33299 33506 33807 37211 37245 37337 37339 37343 37501 37890 37892 37908 37912-37913 37925 37965 38021 38027 38048 38433 38435 38812 39188 39223 39233 39323 39365 39405 39774 39918 39935 39940 40492 40555 41093 41382 41406 41433 41463 41466 41566 41581 41593 41622 41646 41663 41670 41676 41679 41688 41691 41693 41701 41707 41709 41742 41759-41760 41769 41784 41811 41813 41822 41826 41837 41879 41897 41920 41945 41967 42044 42149 42156 42168 42171 42209 42213-42214 42227 42233 42254 42310 42314 42349 42370 42387-42388 42419 42433 42436-42437 42439 42443 42454-42455 42486 42493 42495-42497 42514 42529 42561 42608 42757 42840-42841 43013 43029 43047 43064 43085 43107 43130 43140 43155 43174 43227 43235 43559 45373 45725 47016 47717 47867 47921 48488 48537 48822 48879https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/447/1673?format=asciiOpticaldefaultJ/MNRAS/447/1673/table4Derived Parameters and distances for 209 likely PAGB stars in the Torun catalogue, ordered by Galactic longitude (table 4 in the paper)SimbadNameSimbad column added by the CDSmeta.idcharIRASIRAS designationmeta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
