cds-question@unistra.frsurveyspre-main-sequence-starsyoung-stellar-objectsinfrared-photometryWe performed a deep wide-field (6.76 square-degrees) near-infrared survey with the VISTA telescope that covers the entire extent of the Carina nebula complex. Complementing the VISTA near-infrared catalog with Spitzer IRAC mid-infrared photometry improves the situation of the background contamination considerably. We find that a (J-H) versus (Ks-[4.5]) color-color diagram is well suited to tracing the population of YSO-candidates (cYSOs) by their infrared excess. We identify 8781 sources with strong infrared excess, which we consider as cYSOs. This sample is used to investigate the spatial distribution of the cYSOs with a nearest-neighbor analysis. The surface density distribution of cYSOs agrees well with the shape of the clouds as seen in our Herschel far-infrared survey. The strong decline in the surface density of excess sources outside the area of the clouds supports the hypothesis that our excess-selected sample consists predominantly of cYSOs with a low level of background contamination.2016A&A...585A..49Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/585/A49CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/572/A116 : The VISTA Carina Nebula Survey (Preibisch+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/585/A49https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/585/A49http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/585/A49https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/585/A49https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/585/A49http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/585/A49GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/585/A49/catalog (Infrared excess sources for the Vista Carina Nebula Survey with combined Spitzer data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/585/A49/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/585/A49/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/585/A49/catalog?GETtext/xml+votable180.050000true158.44425-59.86041670.0055555555555555565/9504 6/37247 37333-37335 37341 37930-37931 37934 38020 38024-380257.952274030004205e-20 1.0188844282367877e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/585/A49?format=asciiInfrareddefaultJ/A+A/585/A49/catalogInfrared excess sources for the Vista Carina Nebula Survey with combined Spitzer datarecnoRecord number assigned by the VizieR team.
