cds-question@unistra.fropen-star-clustersx-ray-sourcesastronomical-object-identificationWe present the first high spatial resolution X-ray study of NGC 2244, the 2Myr old stellar cluster in the Rosette Nebula, using Chandra. Over 900 X-ray sources are detected; 77% have optical or FLAMINGOS NIR stellar counterparts and are mostly previously uncataloged young cluster members.2008ApJ...675..464Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/675/464CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/284 : The USNO-B1.0 Catalog (Monet+ 2003)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/ApJ/454/151 : OB Associations of the Northern Milky Way (Massey+ 1995)J/A+A/384/890 : BVRIHalpha photometry of NGC2244 X-ray stars (Berghoefer+ 2002)J/A+A/446/949 : Open clusters proper motions based on UCAC2 (Dias+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/675/464https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/675/464http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/675/464https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/675/464https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/675/464http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/675/464GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/675/464/catalog (Chandra Main and Secondary Catalog)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/675/464/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/675/464/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/675/464/catalog?GETtext/xml+votable180.050000true97.8098354.884188890.0055555555555555566/222491.1166583743361574e-19 6.118840631666147e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/675/464?format=asciiX-raydefaultJ/ApJ/675/464/catalogChandra Main and Secondary CatalogrecnoRecord number assigned by the VizieR team.
