cds-question@unistra.freclipsing-binary-starsinfrared-photometryvisible-astronomybroad-band-photometryOur photoelectric measurements over the past 30 years and a new solution of the radial velocity curve of the eclipsing star with an elliptical orbit V501 Mon (A8 + F2) allowed us to determine with high accuracy all the main parameters of the system: T1=7380+/-60K, M1=(1.66+/- 0.03)M_{sun}_, R1=(1.90+/-0.02)R_{sun}_, T2=6920+/-30K, M2=(1.47+/-0.02)M_{sun}_, R2=(1.58+/-0.01)R_{sun}_. The photometric parallax determined in the study coincides with the Gaia value 0.00103" within the error limits. For the first time, the apsidal motion rate dw/dt_obs_=0.022deg/year was accurately measured, which, within the error limits, matches the theoretical value: dw/dt_theor_=0.024deg/year; 70% of this value is a relativistic contribution. The system possibly satisfies the condition of synchronism between rotational and orbital angular momenta. The age of the stars was determined to be 0.95 billion years. The main component is probably a pulsating variable star of the delta Scuti type (DSCT).2025ARep...69..480Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/ARep/69.480CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/ARep/69.480https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/ARep/69.480http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/ARep/69.480https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/ARep/69.480https://vizier.iucaa.in/viz-bin/votable?-source=J/other/ARep/69.480http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/ARep/69.480GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/ARep/69.480/frame (Full Table 4 of the paper)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/ARep/69.480/frame?https://vizier.iucaa.in/viz-bin/conesearch/J/other/ARep/69.480/frame?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/ARep/69.480/frame?GETtext/xml+votable180.050000true100.1035-1.06252780.0055555555555555566/22078 222101.9821045660507152e-19 6.118840631666147e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/ARep/69.480?format=asciiOpticalInfrareddefaultJ/other/ARep/69.480/frameFull Table 4 of the paperrecnoRecord number assigned by the VizieR team.
