cds-question@unistra.frvariable-starseclipsing-binary-starsradial-velocityRadial velocity measurements and sine-curve fits to orbital velocity variations are presented for the ninth set of 10 close binary systems: V395 And, HS Aqr, V449 Aur, FP Boo, SW Lac, KS Peg, IW Per, V592 Per, TU UMi, and FO Vir. The first three are very close, possibly detached, early-type binaries, and all three require further investigation. Particularly interesting is V395 And, whose spectral type is as early as B7/8 for a 0.685 day orbit binary. KS Peg and IW Per are single-line binaries, with the former probably hosting a very low mass star. We have detected a low-mass secondary in an important semidetached system, FO Vir, at q=0.125+/-0.005. The contact binary FP Boo is also a very small mass ratio system, q=0.106+/-0.005. The other contact binaries in this group are V592 Per, TU UMi, and the well-known SW Lac. V592 Per and TU UMi have bright tertiary companions; for these binaries, and for V395 And, we used a novel technique of arranging the broadening functions into a two-dimensional image in phase. The case of TU UMi turned out to be intractable even using this approach, and we have not been able to derive a firm radial velocity orbit for this binary. Three systems of this group were observed spectroscopically before: HS Aqr, SW Lac, and KS Peg.2005AJ....130..767Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/130/767CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/387/850 : Radial velocities of eclipsing binaries (Imbert, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/130/767https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/130/767http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/130/767https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/130/767https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/130/767http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/130/767GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/130/767/stars (Simbad data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/130/767/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/130/767/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/130/767/stars?GETtext/xml+votable180.050000true356.1337546.3802780.0055555555555555566/1441 1680 6844 9922 12092 13699 13777 20047 26368 30040https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/130/767?format=asciiOpticaldefaultJ/AJ/130/767/starsSimbad datarecnoRecord number assigned by the VizieR team.
