cds-question@unistra.frmillimeter-astronomysubmillimeter-astronomypre-main-sequence-starsyoung-stellar-objectsinfrared-sourcesUnderstanding disk evolution and dissipation is essential for studies of planet formation. Transition disks, i.e., disks with large dust cavities and gaps, are promising candidates of active evolution. About two dozen candidates, selected by their Spectral Energy Distribution (SED), have been confirmed to have dust cavities through millimeter interferometric imaging, but this sample is biased toward the brightest disks. The Spitzer surveys of nearby low-mass star-forming regions have resulted in more than 4000 young stellar objects (YSOs). Using color criteria, we selected a sample of ~150 candidates and an additional 40 candidates and known transition disks from the literature. The Spitzer data were complemented by new observations at longer wavelengths, including new JCMT and APEX submillimeter photometry, and WISE and Herschel-PACS mid- and far-infrared photometry. Furthermore, optical spectroscopy was obtained and stellar types were derived for 85% of the sample, including information from the literature. The SEDs were fit to a grid of RADMC-3D disk models with a limited number of parameters: disk mass, inner disk mass, scale height and flaring, and disk cavity radius, where the latter is the main parameter of interest. About 72% of our targets possibly have dust cavities based on the SED. The derived cavity sizes are consistent with imaging/modeling results in the literature, where available. Trends are found with the L_disk_ over L_*_ ratio and stellar mass and a possible connection with exoplanet orbital radii. A comparison with a previous study where color observables are used (Cieza et al., 2010, Cat. J/ApJ/712/925) reveals large overlap between their category of planet-forming disks and our transition disks with cavities. A large number of the new transition disk candidates are suitable for follow-up observations with ALMA.2016A&A...592A.126Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/592/A126CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/712/925 : Transition circumstellar disks in Ophiuchus (Cieza+, 2010)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/592/A126https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/592/A126http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/592/A126https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/592/A126https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/592/A126http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/592/A126GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/592/A126/table (Target properties (tables 8, A1-A3, C1, D1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/592/A126/table?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/592/A126/table?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/592/A126/table?GETtext/xml+votable180.050000true179.306375-79.358750.0055555555555555565/270 292 6/855 859-860 862 1029-1031 1037 1042 1048 1050 1052 1075 1096 1114 1123 1128 1159 1176 1231 1242 1538-1539 23543 23549 23551 24279 28746 29658 30251 30254-30255 30337 30339-30341 30343 30352 30354 30356 30358-30361 30363 30366 36948 36956-36957 37012 37128 38382 41127 41132 41526 42589 42595 42598 42611 42614 42705 42707 42714 42736 42738 42784-42785 42885 42959 42970 42981-42983 42989 42992 42994 44049 44317 44361 47825-47826 47828 47845https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/592/A126?format=asciiRadioInfrareddefaultJ/A+A/592/A126/refsReferencesBibCodeBibCodemeta.bib.bibcodecharAutAuthor's namemeta.bib.authorcharComCommentsmeta.notecharrecnoRecord number assigned by the VizieR team.
