cds-question@unistra.frstellar-associationsinfrared-photometryvisible-astronomybroad-band-photometryccd-photometryWe present a photometric study of I-band variability in the young association Cepheus OB3b. The study is sensitive to periodic variability on time-scales of less than a day, to more than 20d. After rejection of contaminating objects using V, I, R and narrow-band H{alpha} photometry, we find 475 objects with measured rotation periods, which are very likely pre-main-sequence members of the Cep OB3b star-forming region.2010MNRAS.403..545Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/403/545CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/341/805 : UBVI CCD photometry of Cep OB3b (Pozzo+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/403/545https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/403/545http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/403/545https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/403/545https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/403/545http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/403/545GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/403/545/table1 (Photometry for the INT WFC field observed)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/403/545/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/403/545/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/403/545/table1?GETtext/xml+votable180.050000true343.134662562.656938890.005555555555555556Cone search capability for table J/MNRAS/403/545/table2 (Data on the detected periodic variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/403/545/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/403/545/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/403/545/table2?GETtext/xml+votable180.050000true343.8703562.752405560.0055555555555555566/15682-15683 15689https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/403/545?format=asciiOpticalInfrareddefaultJ/MNRAS/403/545/table1Photometry for the INT WFC field observedFieldField number (G1)meta.id;obs.fieldfloatrecnoRecord number assigned by the VizieR team.
