cds-question@unistra.fropen-star-clustersx-ray-sourcesinfrared-photometryWe present results from an X-ray imaging survey of the young cluster NGC 2264, carried out with the European Photon Imaging Cameras (EPIC) on board the XMM-Newton spacecraft. The X-ray data are merged with extant optical and near-infrared photometry, spectral classifications, Halpha emission strengths, and rotation periods to examine the interrelationships between coronal and chromospheric activity, rotation, stellar mass, and internal structure for a statistically significant sample of pre-main-sequence stars. A total of 300 distinct X-ray sources can be identified with optical or near-infrared counterparts. The sources are concentrated within three regions of the cluster: in the vicinity of S Mon, within the large emission/reflection nebulosity southwest of S Mon, and along the broad ridge of molecular gas that extends from the Cone Nebula to the NGC 2264 IRS 2 field.2007AJ....134..999Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/134/999CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/114/2644 : UBVRIHa photometry of NGC2264 (Sung+, 1997)J/A+A/345/521 : BVRI photometry of NGC 2264 (Flaccomio+, 1999)J/AJ/123/1528 : UBV(RI)_C_ and JHK photometry in NGC 2264 (Rebull+, 2002)J/AJ/127/1117 : Halpha emission-line stars in NGC2264 (Reipurth+, 2004)J/AJ/127/2228 : VRI photometry of PMS stars in NGC 2264 OB (Makidon+, 2004)J/A+A/417/557 : Rotation + variability of PMS Stars in NGC 2264 (Lamm, 2004)J/AJ/129/829 : H{alpha} emission stars in NGC 2264 (Dahm+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/134/999https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/134/999http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/134/999https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/134/999https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/134/999http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/134/999GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/134/999/table2 (X-ray source detections in NGC 2264)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/134/999/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/134/999/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/134/999/table2?GETtext/xml+votable180.050000true100.14510.0727780.0055555555555555566/23637 236391.5062136169708525e-19 1.7003137259100215e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/134/999?format=asciiX-rayInfrareddefaultJ/AJ/134/999/table2X-ray source detections in NGC 2264EEFThroughput of the extraction aperture (4)%phys.size;arith.ratiointEExpEffective exposure time (5)kstime.duration;obs.exposurefloatAVV band extinction (6)magphys.absorption;em.opt.VfloatlogLXLog of foreground extinction corrected X-ray luminositylog(1e-07W)phys.luminosity;em.X-rayfloate_logLXUncertainty in logLXlog(1e-07W)stat.errorfloatVmag?
