cds-question@unistra.frvariable-starspre-main-sequence-starsinfrared-photometryvisible-astronomybroad-band-photometryResults from optical CCD photometric observations of 13 pre-main-sequence stars collected during the period from February 2007 to November 2020 are presented. These stars are located in the association Cepheus OB3, in the field of the young star V733 Cephei. Photometric observations, especially concerning the long-term variability of the stars, are missing in the literature. We present the first long-term V(RI)c monitoring for them, that cover 13 years. Results from our study indicate that all of the investigated stars manifest strong photometric variability. The presented paper is a part of our program for the photometric study of pre-main-sequence stars located in active star-forming regions.2021RAA....21..192Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RAA/21.192CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/556/A60 : BVRI observations of the FUor star V582 AurJ/A+A/568/A49 : Pre-main sequence stars long term phot.J/other/RAA/14.1264 : V350 Cep UBVRI long-term photometry (Ibryamov+, 2014)J/other/PASA/32.11 : Long-term UBVRI photometry of GM Cep (Semkov+, 2015)J/other/PASA/32.21 : Long-Term Multicolour Photometry of YSOs (Ibryamov+ 2015)J/other/BAJ/22.3 : BVRI photometry of 5 PMS stars (Ibryamov+, 2015)J/other/BAJ/24.62 : BVRI Photometry of 14 PMS stars (Ibryamov+, 2016)J/other/RAA/17.20 : V977 Cep & V982 Cep long-term photometry (Ibryamov+ 2017)J/other/PASA/35.7 : Long-term BVRI photometry of V2492 Cygni (Ibryamov+ 2018)J/other/BAJ/29.10 : Long-term BVRI photometry of V1704 Cygni (Ibryamov+ 2018)J/other/RAA/18.137 : Long-term BVRI phot. of 15 PMS stars (Ibryamov+, 2018)J/other/Ser/199.39 : Long-Term Photometry of five PMS stars (Semkov+, 2019)J/other/Ser/202.31 : Long-term BVRI photometry of V900 Mon (Semkov+, 2021)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/RAA/21.192https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RAA/21.192http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RAA/21.192https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RAA/21.192https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RAA/21.192http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RAA/21.192GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RAA/21.192/stars (List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/21.192/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/21.192/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/21.192/stars?GETtext/xml+votable180.050000true342.98112562.30472220.0055555555555555566/15682-156832.367228618189496e-19 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RAA/21.192?format=asciiOpticalInfrareddefaultJ/other/RAA/21.192/starsList of studied starsSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
