cds-question@unistra.frstellar-associationspre-main-sequence-starsinfrared-sourcesThe results of an ISOCAM survey of the R CrA star formation region are presented. The survey was carried out in two broad-band filters, LW2 (5-8.5{mu}m) and LW3 (12-18{mu}m). Although it was not possible to map the densest, central region due to saturation problems, 21 sources were identified which showed mid-IR excesses. Most of these sources have not previously been recognised as YSOs (Young Stellar Objects), mainly because they are relatively faint. We find evidence for a population of very low mass stars which are probably brown dwarfs in their early contraction phases.1999A&A...350..883Ohttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/350/883CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/397/520 : IRAS observations in Cr A (Wilking+, 1992)J/A+A/357/219 : Cha I ISOCAM observations (Persi+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/350/883https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/350/883http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/350/883https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/350/883https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/350/883http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/350/883GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/350/883/table1 (ISOCAM sources with mid-IR excesses)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/350/883/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/350/883/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/350/883/table1?GETtext/xml+votable180.050000true284.733596-37.1270060.005555555555555556Cone search capability for table J/A+A/350/883/table2 (YSOs without detected mid-IR excesses)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/350/883/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/350/883/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/350/883/table2?GETtext/xml+votable180.050000true284.881351-36.8410270.005555555555555556Cone search capability for table J/A+A/350/883/list (Full list of identified ISOCAM sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/350/883/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/350/883/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/350/883/list?GETtext/xml+votable180.050000true284.672522-36.8617330.0055555555555555566/47742 47825 478281.3891223550672228e-20 2.9648415588362266e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/350/883?format=asciiInfrareddefaultJ/A+A/350/883/table1ISOCAM sources with mid-IR excessesrecnoRecord number assigned by the VizieR team.
