Recent studies suggest that star clusters often exhibit a hierarchical structure, possibly resulting from several star formation episodes occurring sequentially rather than a monolithic cloud collapse. We aim to explore the structure of the open cluster and star-forming region NGC 2264 (~3Myr), which is one of the youngest, richest and most accessible star clusters in the local spiral arm of our Galaxy; we link the spatial distribution of cluster members to other stellar properties such as age and evolutionary stage to probe the star formation history within the region. We combined spectroscopic data obtained as part of the Gaia-ESO Survey (GES) with multi-wavelength photometric data from the Coordinated Synoptic Investigation of NGC 2264 (CSI 2264) campaign. We examined a sample of 655 cluster members, with masses between 0.2 and 1.8M_{sun}_ and including both disk-bearing and disk-free young stars. We used Teff estimates from GES and g,r,i photometry from CSI 2264 to derive individual extinction and stellar parameters.2018A&A...609A..10Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/609/A10CatalogResearchIsServedByTAP 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/127/1117 : Halpha emission-line stars in NGC2264 (Reipurth+, 2004)J/AJ/138/1116 : A Spitzer view of NGC 2264 (Sung+, 2009)J/A+A/455/903 : ACIS-I observations of NGC 2264 (Flaccomio+, 2006)J/ApJ/741/35 : NIR photometry and polarization in NGC 2264 (Kwon+, 2011)J/A+A/570/A82 : Mapping accretion variability in NGC 2264 (Venuti+, 2014)J/A+A/581/A66 : UV variability and accretion in NGC 2264 (Venuti+, 2015)J/MNRAS/453/2006 : NGC 2264 SCUBA-2 observations (Buckle+, 2015)J/A+A/590/A78 : NGC2264 weak-line T Tauri lithium abundances (Bouvier+ 2016)J/A+A/586/A47 : Accretion process in NGC 2264 (Sousa+, 2016)J/A+A/599/A23 : Accretion-rotation connection in NGC 2264 (Venuti+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/609/A10https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/609/A10http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/609/A10https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/609/A10https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/609/A10http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/609/A10GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/609/A10/tableb1 (List of the Gaia-ESO Survey targets in the NGC2264 field and of their CSI 2264 counterpart)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/609/A10/tableb1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/609/A10/tableb1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/609/A10/tableb1?GETtext/xml+votable180.050000true99.849839.700440.0055555555555555566/23636-23637 236392.381800341673347e-19 4.653515163505597e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/609/A10?format=asciiOpticaldefaultJ/A+A/609/A10/tableb1List of the Gaia-ESO Survey targets in the NGC2264 field and of their CSI 2264 counterpartrecnoRecord number assigned by the VizieR team.
