cds-question@unistra.fropen-star-clustersstellar-associationsx-ray-sourcessurveysThe distribution of young stars found in the Chandra Carina Complex Project (CCCP) is examined for clustering structure. X-ray surveys are advantageous for identifying young stellar populations compared to optical and infrared surveys in suffering less contamination from nebular emission and Galactic field stars. The analysis is based on smoothed maps of a spatially complete subsample of ~3000 brighter X-ray sources classified as Carina members and ~10000 stars from the full CCCP sample. The principal known clusters are recovered, and some additional smaller groups are identified. No rich embedded clusters are present, although a number of sparse groups are found. The CCCP reveals considerable complexity in clustering properties.2011ApJS..194....9Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/194/9CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/194/2 : Chandra Carina Complex Project (CCCP) catalog (Broos+, 2011)J/ApJS/194/4 : Source classifier for X-ray sources (Broos+, 2011)J/ApJS/194/5 : Carina OB stars in the CCCP catalog (Gagne+, 2011)J/ApJS/194/10 : NIR properties of YSO in the CCCP (Preibisch+, 2011)J/ApJS/194/14 : A Pan-Carina YSO catalog (Povich+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/194/9https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/194/9http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/194/9https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/194/9https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/194/9http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/194/9GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/194/9/table1 (Principal clusters of X-ray stars in the Carina star-forming complex (see section 3.1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/9/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/9/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/9/table1?GETtext/xml+votable180.050000true160.9875-59.5477780.005555555555555556Cone search capability for table J/ApJS/194/9/table2 (Small groups of X-ray stars outside of major clusters)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/9/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/9/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/9/table2?GETtext/xml+votable180.050000true160.55625-59.5997220.005555555555555556Cone search capability for table J/ApJS/194/9/table3 (Carina cluster membership)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/9/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/9/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/9/table3?GETtext/xml+votable180.050000true159.79145806-59.787378890.0055555555555555566/37333 37335 37930 37931 38016 38017 38018https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/194/9?format=asciiX-raydefaultJ/ApJS/194/9/table1Principal clusters of X-ray stars in the Carina star-forming complex (see section 3.1)CntrContour (3)meta.bib.figcharrecnoRecord number assigned by the VizieR team.
