cds-question@unistra.frspectroscopic-binary-starsradial-velocitystellar-masseseffective-temperatureOrbital elements of 37 single-lined spectroscopic binary systems (SB1s) and 5 double-lined spectroscopic binary systems (SB2s) were determined using high-dispersion spectroscopy. To determine the orbital elements accurately, we carried out precise Doppler shift measurements using the HIgh Dispersion Echelle Spectrograph mounted on the Okayama Astrophysical Observatory 1.88 m telescope. We achieved a radial-velocity precision of ~10 m.s^-1^ over seven years of observations. The targeted binaries have spectral types between F5 and K3, and are brighter than the 7th magnitude in the V band. The orbital elements of 28 SB1s and 5 SB2s were determined at least 10 times more precisely than previous measurements. Among the remaining nine SB1s, five objects were found to be single stars, and the orbital elements of four objects were not determined because our observations did not cover the entire orbital period. We checked the absorption lines from the secondary star for 28 SB1s and found that three objects were in fact SB2s.2013AJ....145...41Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/145/41CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sb9 : 9th Catalogue of Spectroscopic Binary Orbits (Pourbaix+ 2004-2014)V/136 : Teff and metallicities for Tycho-2 stars (Ammons+, 2006)I/239 : The Hipparcos and Tycho Catalogues (ESA 1997)III/135 : Henry Draper Catalogue and Extension (Cannon+ 1918-1924; ADC 1989)J/A+A/465/257 : Radial velocity in multiple systems (Tokovinin+, 2007)J/A+A/473/829 : Orbital elements of 156 spectros. binaries (Mermilliod+, 2007)J/ApJS/141/503 : Radial Velocities for 889 late-type stars (Nidever+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/145/41https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/145/41http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/145/41https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/145/41https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/145/41http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/145/41GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/145/41/table1 (Targets of the radial velocity measurements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/145/41/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/145/41/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/145/41/table1?GETtext/xml+votable180.050000true13.267487561.123969440.0055555555555555566/535 2075 2445 3036 5330 7229 7238 7390 8109 8716 8788 9327 10899 11620 12400 14277 17137 17814 17860 18422 18636 18666 18675 18881 23575 23652 23738 23921 24460 26137 26462 28433 30217 31057 31101 32067 32158 32549 40821 44411 44879 44887https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/145/41?format=asciiOpticaldefaultJ/AJ/145/41/table1Targets of the radial velocity measurementsrecnoRecord number assigned by the VizieR team.
