cds-question@unistra.frplanetary-nebulaeinfrared-sourcesstellar-distanceIt is well known that the IRAS colors of planetary nebulae (PNe) are very similar to blackbody colors. Taking account of this characteristic, we define a new method to obtain some information about the distance to PNe by blackbody fitting of IRAS four-band fluxes, assuming these fluxes are due to thermal emission from the nebular dust envelope. The fit should have two free parameters - the dust temperature TD and the distance-dependent "scaling factor" A - under the assumption of uniform dust mass. We find that the A-values have a good correlation with published distances. The scaling factor A could be a more effective distance scale than others, because many PNe have been detected as IRAS sources and the extinction of IRAS fluxes is not so severe, and is known. We also find that TD is concentrated between 100 and 200K, with a typical value of about 150K.1998AJ....115.1989Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/115/1989CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/84 : Strasbourg-ESO Catalogue of Galactic Planetary Nebulae (Acker+, 1992)II/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/115/1989https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/115/1989http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/115/1989https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/115/1989https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/115/1989http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/115/1989GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/115/1989/table3 (Results of the blackbody fitting of iras fluxes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/115/1989/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/115/1989/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/115/1989/table3?GETtext/xml+votable180.050000true273.3247958-32.32853890.0055555555555555565/3590 7182 7194-7195 7205 7211 6/361 1051 1200 1223 1238 1244 1351 1399 1552 1562 1967 2558 2883 2887 2979 2993 3039 3152 3199 3291 3324 3332 3353 3365 3637 3732 3819 4244 4690 5996 6146 6292 9233 9276 9806 12222 12515 12577 12812 12852 12857 12907 12944 12960 12963 12971 12983-12985 12992 13036 13039 13044 13055 13676 13796 13814 13968 14005 14011 14060 14063 14076 14118 14140 14214 14239 14258 14263 14279 14282 14338-14339 14344 14390 14402 14415 14428-14429 14443 14452 14460 14482 14491 14592 14596 14606 14642 14654-14655 14660 14786 14796 14853 15172 15377 15384 15407 15425 15428 15435 15437 15451 15472-15473 15481 15552 15621 15632 15639 15681 15721 15739 15752 19741 20776 20816 20826 20829 20951 21215 21315 21523 21600 21609 22083 22093 22137 22166 22280 22660 23389 23658 23704 23816 23949 24036 24361 25008 28675 28685 28703 28711 28716-28718 28722-28723 28726 28732-28734 28746 28766 28772 28774-28775 28791 28794-28798 28805 28819 28825 28835-28836 28838 28840-28841 28843 28849-28851 28854 28856-28858 28860 28863-28865 28867-28868 28870-28872 28881 28885-28886 28889 28906-28907 28911 28917 28922-28923 28941 28943 28963 28973 28975 28977 28986 28991 29024 29037 29056-29058 29062-29063 29078 29083 29086-29087 29092 29094 29096 29104 29130 29134 29146-29147 29150 29155 29160 29168 29177 29182 29189 29193 29198 29200-29202 29205-29206 29213 29236 29253-29255 29257 29259-29262 29266-29267 29269 29274 29276 29286 29296-29297 29309 29317 29326 29350 29405 29427 29442-29443 29448 29451 29454 29466 29470 29472 29520 29523 29527 29531 29537 29540 29566 29613 29654 29718 29852 29859 29866 29868 29870 29886 29899 30110 30208-30209 30214 30221 30225-30227 30247 30264 30266 30276 30282-30283 30288 30297 30303 30305 30308 30327-30328 30340 30349 30357-30358 30364 30385 30389 30403 30431 30435 30491 30498 30504-30505 30511 30518 30527 30615 30621 30631 30635 30637 30656 30658 30665 30675 30684 30686-30687 30697 30699 30711 30803 31026 31775 31847 31895 32001 32042 32068 32070-32071 32078 32080 32083 32101 32109 32193 32372 32571 33029 36130 36938 37006 37110 37151 37191 37212 37234 37322-37324 37337 37348 37354 37361 37661 37701 37710 37731 37733-37735 37745 37835 37870 37890 37914-37915 37918 37930 37934 37959 37963 38001 38022-38023 38028 38031 38034 38043 38063 38075 38433 38436 38512 38538 38563 39029 39194 39198 39251 39261 39279-39280 39363 39384 39717 39775 39801 39822 39935 39956 40070 40120 40130 40279 40510 40571 40621 41145 41174 41186 41268 41336 41371 41434 41439 41442 41448 41463-41464 41470-41471 41495 41574 41576 41580 41596 41617 41646 41663-41664 41674 41679 41690 41713 41715 41732 41748 41789 41792-41793 41799 41803 41826 41831-41832 41837 41842 41849 41886 41903 41920 41946 42088 42094 42098-42099 42125 42147 42151 42160 42162 42168 42180 42192 42209 42222 42232 42267 42295-42296 42312-42313 42315 42321 42335 42354-42355 42357 42360 42363 42375 42389 42394 42425 42427 42437 42446 42454 42460 42464 42478-42479 42490 42493-42494 42505 42511-42512 42521 42579 42599 42632 42664 42709 42711 42753 42771 42773 42775 42779 42792 42835 42853 42872 43012 43016 43018 43021 43035 43078 43139 43268 43296 43360 44048 44416 45243 46712 47100 47466 47627 47663 47711 47793 47859 47921 48032 48776 489511.6558465556080236e-21 2.1346512726771855e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/115/1989?format=asciiInfrareddefaultJ/AJ/115/1989/table3Results of the blackbody fitting of iras fluxesrecnoRecord number assigned by the VizieR team.
