cds-question@unistra.frspectroscopic-binary-starsradial-velocityWe present a new set of radial-velocity measurements of the spectroscopic binary star HD 165052 obtained by disentangling of high-resolution optical spectra. The longitude of the periastron ({varpi}=60+/-2{deg}) shows a variation with respect to previous studies. We have determined the apsidal motion rate of the system {dot{varpi}}=12.1+/-0.3{deg}/yr, which was used to calculate the absolute masses of the binary components: M_1_=22.5+/-1.0M_{sun}_ and M_2_=20.5+/-0.9M_{sun}_. Analysing the separated spectra we have re-classified the components as O7Vz and O7.5Vz stars.2013MNRAS.433.1300Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/433/1300CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/433/1300https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/433/1300http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/433/1300https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/433/1300https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/433/1300http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/433/1300GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/MNRAS/433/1300/tableb1Radial velocities of HD 165052 previously reportedl_HJD[~] Limit flag on HJDmeta.code.error;time.epochcharrecnoRecord number assigned by the VizieR team.
