cds-question@unistra.fropen-star-clusterspre-main-sequence-starsyoung-stellar-objectsphotometryThe low spin rates measured for solar-type stars at an age of a few Myr (~10% of the break-up velocity) indicate that some mechanism of angular momentum regulation must be at play in the early pre-main sequence. This may be associated with magnetospheric accretion and star-disk interaction, as suggested by observations that disk-bearing objects (CTTS) are slower rotators than diskless sources (WTTS) in young star clusters. We characterize the rotation properties for members of the star-forming region NGC 2264 (~3Myr) as a function of mass, and investigate the accretion-rotation connection at an age where about 50% of the stars have already lost their disks. We examined a sample of 500 cluster members (40% with disks, 60% without disks), distributed in mass between ~0.15 and 2M_{sun}_, whose photometric variations were monitored in the optical for 38 consecutive days with the CoRoT space observatory. Light curves were analyzed for periodicity using three different techniques: the Lomb-Scargle periodogram, the autocorrelation function and the string-length method. Periods were searched in the range between 0.17-days (i.e., 4h, twice the data sampling adopted) and 19-days (half the total time span). Period detections were confirmed using a variety of statistical tools (false alarm probability, Q-statistics), as well as visual inspection of the direct and phase-folded light curves.2017A&A...599A..23Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/599/A23CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/430/1433 : NGC 2264 members periods with CoRoT (Affer+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/599/A23https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/599/A23http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/599/A23https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/599/A23https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/599/A23http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/599/A23GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/599/A23/table4 (Identifier, coordinates, classification, light curve type, mass, period detections for NGC 2264 members probed in this study (table F1 in the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/599/A23/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/599/A23/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/599/A23/table4?GETtext/xml+votable180.050000true100.321459.894350.0055555555555555566/23636-23637 23639https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/599/A23?format=asciidefaultJ/A+A/599/A23/table4Identifier, coordinates, classification, light curve type, mass, period detections for NGC 2264 members probed in this study (table F1 in the paper)Mass?
