These stars are located in the young open cluster Trumpler 37, in the field of GM Cephei. The observational data indicate that all stars from our study exhibit variability in all-optical passbands, typical for young stars. In this paper, we describe and discuss the photometric behavior of the stars and the possible reasons for their variability. For two of the objects, we identified periodicity in their light variation.2023RAA....23h5006Ihttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/RAA/23.H5006CatalogResearchIsServedByTAP 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/23.H5006https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/RAA/23.H5006http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/RAA/23.H5006https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/RAA/23.H5006https://vizier.iucaa.in/viz-bin/votable?-source=J/other/RAA/23.H5006http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/RAA/23.H5006GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/RAA/23.H5006/stars (List of studied stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/RAA/23.H5006/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/other/RAA/23.H5006/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/RAA/23.H5006/stars?GETtext/xml+votable180.050000true324.211333357.51963890.0055555555555555566/15478-154792.367228618189496e-19 4.920466254354166e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/RAA/23.H5006?format=asciiOpticalInfrareddefaultJ/other/RAA/23.H5006/starsList of studied starsSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
