cds-question@unistra.frmagellanic-cloudsorbitsgiant-starsModelling ellipsoidal variables with known distances can lead to exact determination of the masses of both components, even in the absence of eclipses. We present such modelling using light and radial velocity curves of ellipsoidal red giant binaries in the Large Magellanic Cloud (LMC), where they are also known as sequence E stars. Stars were selected as likely eccentric systems on the basis of light curve shape alone. We have confirmed their eccentric nature and obtained system parameters using the Wilson-Devinney code.2012MNRAS.421.2616Nhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/421/2616CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AcA/54/347 : IVB mag of LMC ellipsoidal variables (Soszinski+, 2004)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/421/2616https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/421/2616http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/421/2616https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/421/2616https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/421/2616http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/421/2616GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/421/2616/table13 (Candidate eccentric ellipsoidal variables in the OGLE II data base (table1) and initial parameters (table3))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/421/2616/table13?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/421/2616/table13?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/421/2616/table13?GETtext/xml+votable180.050000true80.0562917-69.38144440.0055555555555555566/33096-33098https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/421/2616?format=asciidefaultJ/MNRAS/421/2616/table13Candidate eccentric ellipsoidal variables in the OGLE II data base (table1) and initial parameters (table3)TeffEffective temperatureKphys.temperature.effectivefloatVCVelocity curvemeta.ref.urlcharTabNumber of the table with solutionsmeta.numberintSolDisplay the solutions for this starmeta.ref.urlcharRVDisplay radial velocitiesmeta.ref.urlchar_RAPosition from OGLE name (right ascension part)degpos.eq.ra;meta.main_DEPosition from OGLE name (declination part)degpos.eq.dec;meta.mainrecnoRecord number assigned by the VizieR team.
