cds-question@unistra.fryoung-stellar-objectsx-ray-sourcesinfrared-photometrysurveysinterstellar-mediuminterferometryproper-motionsWe present Spitzer Space Telescope IRAC and MIPS observations of a 0.85deg^2^ field including the Corona Australis (CrA) star-forming region. At a distance of 130pc, CrA is one of the closest regions known to be actively forming stars, particularly within its embedded association, the Coronet. Using the Spitzer data, we identify 51 young stellar objects (YSOs) in CrA which include sources in the well-studied Coronet cluster as well as sources distributed throughout the molecular cloud. Twelve of the YSOs discussed are new candidates, one of which is located in the Coronet. Known YSOs retrieved from the literature are also added to the list, and a total of 116 candidate YSOs in CrA are compiled. A clustering analysis was also performed, finding that the main cluster core, consisting of 68 members, is elongated (having an aspect ratio of 2.36), with a circular radius of 0.59pc and mean surface density of 150pc^-2^. In addition, we analyze outflows and jets in CrA by means of new CO and H2 data. We present 1.3mm interferometric continuum observations made with the Submillimeter Array (SMA) covering R CrA, IRS 5, IRS 7, and IRAS 18595-3712 (IRAS 32).2011ApJS..194...43Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/194/43CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIX/30 : Second ROSAT PSPC Catalog (ROSAT, 2000)V/73 : Emission-Line Stars of the Orion Population (Herbig+ 1988)J/ApJS/185/198 : The Cepheus flare observed with IRAC and MIPS (Kirk+, 2009)J/ApJS/184/18 : Spitzer survey of young stellar clusters (Gutermuth+, 2009)J/ApJ/680/495 : Survey of Interstellar clouds in the Gould belt (Harvey+,J/ApJ/674/336 : Spitzer observations of NGC 1333 (Gutermuth+, 2008)J/A+A/488/987 : Near-infrared survey of R CrA cloud (Haas+, 2008)J/A+A/475/959 : X-ray properties of young stellar objects (Forbrich+, 2007)J/A+AS/146/323 : RASS young sources around R CrA (Neuhaeuser+, 2000)J/A+A/350/883 : R CrA ISOCAM observations (Olofsson+, 1999)J/ApJ/397/520 : IRAS observations in Cr A (Wilking+, 1992)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/194/43https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/194/43http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/194/43https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/194/43https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/194/43http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/194/43GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/194/43/table7 (Spitzer matches to known YSOs and candidate YSOs in CrA)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/43/table7?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/43/table7?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/43/table7?GETtext/xml+votable180.050000true285.473625-36.95222220.005555555555555556Cone search capability for table J/ApJS/194/43/table11 (Identified knots in the CrA star-forming region)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/43/table11?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/43/table11?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/43/table11?GETtext/xml+votable180.050000true285.10057917-36.968666670.005555555555555556Cone search capability for table J/ApJS/194/43/YSOs (YSO candidates in CrA MCld based on Spitzer IRAC and MIPS , on 2MASS and MIPS or Class III YSO candidates from Spitzer and ROSAT)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/43/YSOs?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/43/YSOs?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/43/YSOs?GETtext/xml+votable180.050000true284.1656667-37.12244440.0055555555555555566/47739 47742 47824 47825 47827 478282.4016587514425055e-21 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/194/43?format=asciiX-rayInfrareddefaultJ/ApJS/194/43/table7Spitzer matches to known YSOs and candidate YSOs in CrASimbadNameSimbad column added by the CDSmeta.idcharNameObject identification (1)meta.id;meta.maincharl_F8.0Limit flag on F8.0meta.code.errorcharrecnoRecord number assigned by the VizieR team.
