cds-question@unistra.freclipsing-binary-starsinfrared-photometryvisible-astronomybroad-band-photometryDifferential UBV photoelectric photometry for the eclipsing binary MY Cyg is presented. The Wilson-Devinney program is used to simultaneously solve the three light curves together with previously published radial velocities. A comparison is made with the previous solution found with the Russell-Merrill method. We examine the long-term apsidal motion of this well-detached, slightly eccentric system. We determine absolute dimensions, discuss metallicity/Am-star issues, and estimate the evolutionary status of the stars.2009AJ....137.2949Thttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/137/2949CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/137/2949https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/137/2949http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/137/2949https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/137/2949https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/137/2949http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/137/2949GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tap3.322582951404819e-19 6.118840631666147e-19OpticalInfrareddefaultJ/AJ/137/2949/table1MY Cyg photometric observationsrecnoRecord number assigned by the VizieR team.
