cds-question@unistra.frmultiple-starsspectroscopic-binary-starsinfrared-sourceschemically-peculiar-starsPost-AGB binaries are surrounded by massive disks of gas and dust that are similar to protoplanetary disks surrounding young stars. We assembled a catalog of all known Galactic post-AGB binaries with disks. We explore correlations between the different observables with the aim to learn more about potential disk-binary interactions. We compiled spectral energy distributions of 85 Galactic post-AGB binary systems. We built-up a color-color diagram to differentiate between the different disk morphologies traced by the characteristics of the infrared excess. We categorised different disk types and looked for correlations with other observational characteristics of these systems. 8 to 12% of our targets are surrounded by transition disks, i.e. disks having no or low near-infrared excesses. We find a strong link between these transition disks and the depletion of refractory elements seen on the surface of the post-AGB star. We interpret this correlation as evidence for the presence of a mechanism that stimulates the dust and gas separation within the disk and which also produces the transition disk structure. We propose that such a mechanism can be a giant planet carving a hole in the disk which traps the dust in the outer disk parts. We propose two disk evolutionary scenarios, depending on the presence of such a giant planet in the disk. We advocate that giant planets can successfully explain the correlation between the transition disks and the depletion of refractory materials observed in post-AGB binaries. If the planetary scenario is confirmed, disks around post-AGB binaries could be a unique laboratory to test planet-disk interactions and their influence on the late evolution of binary stars. Whether the planets are first or second generation also remains to be studied. We argue that these disks are the perfect place to study planet formation scenarios in an unprecedented parameter space.2022A&A...658A..36Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/658/A36CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/453/133 : WISE view of RV Tauri stars (Gezer+, 2015)J/A+A/620/A85 : Binary post-AGB stars radial velocities (Oomen+, 2018)J/MNRAS/508/2226 : Binary central star of V510 Pup (Manick+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/658/A36https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/658/A36http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/658/A36https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/658/A36https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/658/A36http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/658/A36GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/658/A36/table1 (Full list of Galactic sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/658/A36/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/658/A36/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/658/A36/table1?GETtext/xml+votable180.050000true26.445958333346.81693611110.0055555555555555566/1096 2495 3333 7064 8490 12685 12851 12948 12955 13043 13046 13185 13187 13559 13729 14245 14253 14480 14559 14642 14738 14770 14929-14930 20921 21090 21326 21567 21931 22114 22450 23660 23768 23821 24325 24394 24434 25501 28722 28738 29378 29579 29869 29935 30221 30225 30498 30562 31766 32181 32562 32607 36973 37245 37306 37841 37881 37915 37942 37965 38021 38812 39395 39629 39664 39918 40046 40491 41093 41212 41339 41471 41531 41815 42011 42127 42197 42295 42338 42802 43107 43535 43559 43651 47961https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/658/A36?format=asciiInfrareddefaultJ/A+A/658/A36/table1Full list of Galactic sourcesH-KsH-Ks colormagphot.color;em.IR.H;em.IR.KfloatrecnoRecord number assigned by the VizieR team.
