cds-question@unistra.frinfrared-photometryopen-star-clustersastronomical-object-identificationyoung-stellar-objectsWe have performed mid-IR photometry of the young open cluster NGC 2264 using the images obtained with the Spitzer Space Telescope Infrared Array Camera and Multiband Imaging Photometer for Spitzer instruments and presented a normalized classification scheme of young stellar objects in various color-color diagrams to make full use of the information from multicolor photometry. These results are compared with the classification scheme based on the slope of the spectral energy distribution (SED). From the spatial distributions of Class I and II stars, we have identified two subclusterings of Class I objects in the CONE region of Sung et al. (Cat. J/AJ/135/441). The disked stars in the other star-forming region S Mon are mostly Class II objects. In addition, we have derived a somewhat higher value of the primordial disk fraction for NGC 2264 members located below the main pre-main-sequence locus (so-called BMS stars). This result supports the idea that BMS stars are young stars with nearly edge-on disks.2009AJ....138.1116Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/138/1116CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/138/963 : NGC 2264 members vsini (Baxter+, 2009)J/AJ/135/441 : VRIH{alpha} photometry in NGC 2264 (Sung+, 2008)J/ApJ/671/605 : NGC 2264 and ONC PMS stars in the infrared (Cieza+, 2007)J/AJ/134/999 : X-ray observations of NGC 2264 (Dahm+, 2007)J/ApJ/642/972 : IR photometry of a star-forming core in NGC 2264 (Young+,J/A+A/455/903 : ACIS-I observations of NGC 2264 (Flaccomio+, 2006)J/AJ/129/829 : H{alpha} emission stars in NGC 2264 (Dahm+, 2005)J/A+A/430/1005 : VRIH{alpha} photometry of NGC 2264 variables (Lamm+, 2005)J/AJ/128/1684 : NGC 2264: VRIH{alpha} photometry (Sung+, 2004)J/AJ/127/1117 : Halpha emission-line stars in NGC2264 (Reipurth+, 2004)J/A+A/417/557 : Rotation + variability of PMS Stars in NGC 2264 (Lamm, 2004)J/AJ/127/2659 : CHANDRA observations of NGC 2264 (Ramirez+, 2004)J/AJ/123/1528 : UBV(RI)_C_ and JHK photometry in NGC 2264 (Rebull+, 2002)J/A+A/355/651 : HRI observations of PMS stars in NGC 2264 (Flaccomio+, 2000)J/AJ/114/2644 : UBVRIHa photometry of NGC2264 (Sung+, 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/138/1116https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/138/1116http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/138/1116https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/138/1116https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/138/1116http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/138/1116GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/138/1116/table2 (Spitzer counterparts of X-ray sources without optical or 2MASS counterparts)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/138/1116/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/138/1116/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/138/1116/table2?GETtext/xml+votable180.050000true100.08383339.75302780.005555555555555556Cone search capability for table J/AJ/138/1116/table1 (Catalog of sources detected with Spitzer Space Telescope IRAC and MIPS 24 micron)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/138/1116/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/138/1116/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/138/1116/table1?GETtext/xml+votable180.050000true99.92233339.191250.0055555555555555566/23636 23637 236396.772611666688002e-21 6.185923063528282e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/138/1116?format=asciiInfrareddefaultJ/AJ/138/1116/table2Spitzer counterparts of X-ray sources without optical or 2MASS counterpartsrecnoRecord number assigned by the VizieR team.
