cds-question@unistra.freclipsing-binary-starsradial-velocityRadial velocity (RV) measurements and sine curve fits to the orbital RV variations are presented for 10 close binary systems: TZ Boo, VW Boo, EL Boo, VZ CVn, GK Cep, RW Com, V2610 Oph, V1387 Ori, AU Ser, and FT UMa. Our spectroscopy revealed two quadruple systems, TZ Boo and V2610 Oph, while three stars showing small photometric amplitudes, EL Boo, V1387 Ori, and FT UMa, were found to be triple systems. GK Cep is a close binary with a faint third component. While most of the studied eclipsing systems are contact binaries, VZ CVn and GK Cep are detached or semidetached double-lined binaries, and EL Boo, V1387 Ori, and FT UMa are close binaries of uncertain binary type. The large fraction of triple and quadruple systems found in this sample supports the hypothesis of formation of close binaries in multiple stellar systems; it also demonstrates that low photometric amplitude binaries are a fertile ground for further discoveries of multiple systems.2009AJ....137.3646Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/137/3646CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/137/3646https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/137/3646http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/137/3646https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/137/3646https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/137/3646http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/137/3646GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/137/3646/table3 (Spectroscopic orbital elements)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/137/3646/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/137/3646/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/137/3646/table3?GETtext/xml+votable180.050000true227.038053139.97024060.0055555555555555566/7225 8419 8656 8716 9890 10301 16145 23797 28143 29671https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/137/3646?format=asciiOpticaldefaultJ/AJ/137/3646/table3Spectroscopic orbital elementsrecnoRecord number assigned by the VizieR team.
