cds-question@unistra.freclipsing-binary-starsinfrared-photometryvisible-astronomybroad-band-photometryOur multicolour photometric measurements of V361 Cam (P=8.64day, V=10.79mag, e=0.12, B5 V + B9 V) over the past 16 years, as well as TESS data, allowed us to determine for the first time the main physical characteristics of the system and measure the apsidal rotation velocity. The following physical parameters of the component stars were obtained: T1=15400+/-300K, M1=(6.0+/-0.4)M_{sun}_, R1=(5.03+/-0.05)R_{sun}_, T2=11700+/-250K, M2=(2.8+/-0.2)M_{sun}_, R2=(1.94+/-0.04)R_{sun}_. The photometric parallax of 0.00035"+/-0.00001" matches the Gaia measurement of 0.00035"+/-0.00003". The apsidal rotation velocity is dw/dt=0.024+/-0.007deg/year, which is less than the theoretical value under the synchronism condition dw/dt=0.056+/-0.006deg/year. The age of the system, assuming solar chemical composition, is 70Myr. Both components are pulsating beta Cephei variables.2025ARep...69..118Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/ARep/69.118CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/ARep/69.118https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/ARep/69.118http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/ARep/69.118https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/ARep/69.118https://vizier.iucaa.in/viz-bin/votable?-source=J/other/ARep/69.118http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/ARep/69.118GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticalInfrareddefaultJ/other/ARep/69.118/ubandU Johnson photometric observations of V361 CamrecnoRecord number assigned by the VizieR team.
