cds-question@unistra.fropen-star-clusterspre-main-sequence-starsvariable-starsphotometryRotation is one of the key stellar parameters which undergo substantial evolution during the stellar lifetime, in particular during the early stages. Stellar rotational periods can be determined on the basis of the periodic modulation of starlight produced by non-uniformities on the surface of the stars, due to manifestation of stellar activity. We present the results of an extensive search for rotational periods among NGC 2264 cluster members, based on photometric monitoring using the COnvection ROtation and planetary Transits (CoRoT) satellite, with particular attention to the distribution of classical and weak-line T-Tauri stars. NGC 2264 is one of the nearest and best studied star forming region in the solar neighbourhood, with an estimated age of 3Myr, and is the object of a recent simultaneous multiband campaign including a new CoRoT observation with the aim to assess the physical origin of the observed variability. We find that the rotational distributions of classical and weak-line T-Tauri stars are different, suggesting a difference in the rotational properties of accreting and non-accreting stars.2013MNRAS.430.1433Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/430/1433CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tob/corot : CoRoT observation log Release 13 (CoRoT, 2009-2014)J/AJ/114/2644 : UBVRIHa photometry of NGC2264 (Sung+, 1997)J/A+A/345/521 : BVRI photometry of NGC 2264 (Flaccomio+, 1999)J/A+A/355/651 : HRI observations of PMS stars in NGC 2264 (Flaccomio+, 2000)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/127/2659 : CHANDRA observations of NGC 2264 (Ramirez+, 2004)J/AJ/128/1684 : NGC 2264: VRIH{alpha} photometry (Sung+, 2004)J/AJ/129/829 : H{alpha} emission stars in NGC 2264 (Dahm+, 2005)J/A+A/417/557 : Rotation + variability of PMS Stars in NGC 2264 (Lamm, 2004)J/A+A/430/1005 : VRIH{alpha} photometry of NGC 2264 variables (Lamm+, 2005)J/A+A/455/903 : ACIS-I observations of NGC 2264 (Flaccomio+, 2006)J/ApJ/648/1090 : Radial velocities of NGC 2264 stars (Furesz+, 2006)J/AJ/134/999 : X-ray observations of NGC 2264 (Dahm+, 2007)J/ApJ/671/605 : NGC 2264 and ONC PMS stars in the infrared (Cieza+, 2007)J/AJ/135/441 : VRIH{alpha} photometry in NGC 2264 (Sung+, 2008)J/AJ/138/963 : Rotation of NGC 2264 members (Baxter+, 2009)J/AJ/138/1116 : A Spitzer view of NGC 2264 (Sung+, 2009)J/ApJ/741/35 : NIR photometry and polarization in NGC 2264 (Kwon+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/430/1433https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/430/1433http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/430/1433https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/430/1433https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/430/1433http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/430/1433GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/430/1433/table2 (Catalogue of periods for NGC 2264 members)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/430/1433/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/430/1433/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/430/1433/table2?GETtext/xml+votable180.050000true99.765629.673370.0055555555555555566/23636-23637 23639https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/430/1433?format=asciiOpticaldefaultJ/MNRAS/430/1433/table2Catalogue of periods for NGC 2264 membersrecnoRecord number assigned by the VizieR team.
