cds-question@unistra.freclipsing-binary-starsradial-velocityRadial velocity measurements and sine-curve fits to the orbital radial velocity variations are presented for 10 close binary systems: OO Aql, CC Com, V345 Gem, XY Leo, AM Leo, V1010 Oph, V2612 Oph, XX Sex, W UMa, and XY UMa. Most of these binaries have been observed spectroscopically before, but our data are of higher quality and consistency than in the previous studies. While most of the studied eclipsing pairs are contact binaries, V1010 Oph is probably a detached or semidetached double-lined binary, and XY UMa is a detached, chromospherically active system whose broadening functions clearly show well-defined and localized dark spots on the primary component. A particularly interesting case is XY Leo, which is a member of visually unresolved quadruple system composed of a contact binary and a detached, noneclipsing, active binary with an 0.805 day orbital period. V345 Gem and AM Leo are known members of visual binaries. We found faint visual companions at about 2"-3" from XX Sex and XY UMa.2007AJ....133.1977Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/133/1977CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/130/767 : Radial velocity studies of close binary stars (Rucinski+, 2005)J/AJ/132/769 : Radial velocities of 10 close binaries (Pribulla+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/133/1977https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/133/1977http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/133/1977https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/133/1977https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/133/1977http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/133/1977GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/133/1977/stars (Star positions (from Simbad))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/133/1977/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/133/1977/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/133/1977/stars?GETtext/xml+votable180.050000true297.0529179.3088890.0055555555555555566/4427 6354 7262 7273 26850 27481 28432 29374 30565 31812https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/133/1977?format=asciiOpticaldefaultJ/AJ/133/1977/starsStar positions (from Simbad)recnoRecord number assigned by the VizieR team.
