cds-question@unistra.frstellar-associationsx-ray-sourcesinfrared-photometryTrumpler 16 is a well-known rich star cluster containing the eruptive supergiant {eta} Carinae and located in the Carina star-forming complex. In the context of the Chandra Carina Complex Project, we study Trumpler 16 using new and archival X-ray data. A revised X-ray source list of the Trumpler 16 region contains 1232 X-ray sources including 1187 likely Carina members. These are matched to 1047 near-infrared counterparts detected by the HAWK-I instrument at the Very Large Telescope allowing for better selection of cluster members. The cluster is irregular in shape. Although it is roughly circular, there is a high degree of sub-clustering, with no noticeable central concentration and an extension to the southeast. We estimate the total Trumpler 16 pre-main-sequence population to be >6500 Class II and Class III X-ray sources. An overall K-excess disk frequency of ~8.9% is derived using the X-ray-selected sample, although there is some variation among the sub-clusters, especially in the southeastern extension. X-ray emission is detected from 29 high-mass stars with spectral types between B2 and O3.2011ApJS..194...12Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/194/12CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/chandra : The Chandra Archive Log (CXC, 1999-)B/mk : Catalogue of Stellar Spectral Classifications (Skiff, 2010)J/ApJS/194/10 : NIR properties of YSO in the CCCP (Preibisch+, 2011)J/ApJS/194/9 : X-ray star clusters in the Carina complex (Feigelson+, 2011)J/ApJS/194/4 : A Naive Bayes source classifier for Xray sources (Broos+ 2011)J/ApJS/194/2 : Chandra Carina Complex Project (CCCP) catalog (Broos+, 2011)J/A+A/490/1055 : Tr 16 low-mass stars Chandra survey (Albacete-Colombo+, 2008)J/ApJ/589/509 : Chandra observations of Trumpler 14 and 16 (Evans+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/194/12https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/194/12http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/194/12https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/194/12https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/194/12http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/194/12GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/194/12/xsources (Chandra ACIS point sources properties and their XPHOT properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/12/xsources?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/12/xsources?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/12/xsources?GETtext/xml+votable180.050000true161.02204806-59.762068060.005555555555555556Cone search capability for table J/ApJS/194/12/obstars (OB stars in the Trumpler 16 region and their IR properties)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/12/obstars?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/12/obstars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/12/obstars?GETtext/xml+votable180.050000true161.02425-59.58658330.005555555555555556Cone search capability for table J/ApJS/194/12/table6 (High-mass stars in the Trumpler 16 region not detected in X-rays)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/194/12/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/194/12/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/194/12/table6?GETtext/xml+votable180.050000true161.0575-59.71583330.0055555555555555566/380168.650015785639275e-20 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/194/12?format=asciiX-rayInfrareddefaultJ/ApJS/194/12/xsourcesChandra ACIS point sources properties and their XPHOT propertiesrecnoRecord number assigned by the VizieR team.
