cds-question@unistra.fryoung-stellar-objectsinfrared-sourcesWe are searching for Young Stellar Objects (YSOs) near the boundary between protostars and pre-main-sequence objects, what we term Transitional YSOs. We have identified a sample of 125 objects as candidate transitional YSOs on the basis of IRAS colors and the optical appearance on POSS plates. We have obtained optical and near-IR imaging of 82 objects accessible from the Northern Hemisphere and optical images of 62 sources accessible from the South. We also created deconvolved 60{mu}m IRAS images of all sources. We have classified the objects on the basis of their morphology in the optical and near-IR images. We find that the majority of our objects are associated with star-forming regions, confirming our expectation that the bulk of these objects are YSOs. Of the 125 objects, 28 have a variety of characteristics very similar to other transitional YSOs, while another 22 show some of these characteristics. Furthermore we have found seven objects to be good candidates for members of the Herbig Ae/Be stellar group, of which three are newly identified as such.1999A&A...352..228Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/352/228CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)J/ApJ/397/520 : IRAS obs. of YSO in Corona Australis (Wilking+, 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/352/228https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/352/228http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/352/228https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/352/228https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/352/228http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/352/228GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/352/228/table1 (Transitional YSO candidate IRAS sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/352/228/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/352/228/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/352/228/table1?GETtext/xml+votable180.050000true8.07708365.4552780.0055555555555555566/862 1050 1287 1289 1307 1344 1379 1589 1736 1759 1831 1928 1963 3009 3061 3506 3606 3747 3884 4439 12072 13051 14255 14331-14332 14343 14366 14403 14603 14616 14619 14624 14629 14671 14685 14691 15370 15455 15476 15649 15676-15677 16191 16320 18897 20828 21285 21303 21353 21430 21438 21642 21671 21677 22044-22045 22113 22120 22124 22161 22205 22266 22829 23549 23584 23637 23644 23767 24139 24158 24163 24189 24303 24340 24361 24425-24426 24457 24510 28891-28892 29906 30219 30325 30592 30604 30701 33079 37242 37267 37845 37868 37886 37904 38022 38314 39249 39259 39273 39369 39803 39839 39908 39922 41681 41698 41707 41732 41740 41763 41817 42120 42364 42450 42595 42610 43014 43020 43026 43344 47828https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/352/228?format=asciiInfrareddefaultJ/A+A/352/228/table1Transitional YSO candidate IRAS sourcesrecnoRecord number assigned by the VizieR team.
