cds-question@unistra.frspectroscopic-binary-starsradial-velocityIn anticipation of the Gaia astrometric mission, a large sample of spectroscopic binaries has been observed since 2010 with the Spectrographe pour l'Observation des PHenomenes des Interieurs Stellaires et des Exoplanetes spectrograph at the Haute-Provence Observatory. Our aim is to derive the orbital elements of double-lined spectroscopic binaries (SB2s) with an accuracy sufficient to finally obtain the masses of the components with relative errors as small as 1 per cent when the astrometric measurements of Gaia are taken into account. In this paper, we present the results from five years of observations of 10 SB2 systems with periods ranging from 37 to 881d. Using the todmor algorithm, we computed radial velocities from the spectra, and then derived the orbital elements of these binary systems. The minimum masses of the components are then obtained with an accuracy better than 1.2 per cent for the 10 binaries. Combining the radial velocities with existing interferometric measurements, we derived the masses of the primary and secondary components of HIP 87895 with an accuracy of 0.98 and 1.2 per cent, respectively.2016MNRAS.458.3272Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/458/3272CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/337 : Gaia DR1 (Gaia Collaboration, 2016)J/A+A/498/627 : Radial velocities of SB with M giant (Famaey+, 2009)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/458/3272https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/458/3272http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/458/3272https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/458/3272https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/458/3272http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/458/3272GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/458/3272/table1 (10 SB2 analysed in this paper)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/458/3272/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/458/3272/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/458/3272/table1?GETtext/xml+votable180.050000true38.9284963.63486970.0055555555555555566/917 1542 3653 5451 10343 10857 15132 16331 27960 32549https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/458/3272?format=asciiOpticaldefaultJ/MNRAS/458/3272/table110 SB2 analysed in this paperNspNumber of spectra collected with SOPHIE.meta.numberintrecnoRecord number assigned by the VizieR team.
