cds-question@unistra.frspectroscopic-binary-starssurveyseffective-temperatureWe devise a new method for the detection of double-lined binary stars in a sample of the Radial Velocity Experiment (RAVE) survey spectra. The method is both tested against extensive simulations based on synthetic spectra and compared to direct visual inspection of all RAVE spectra. It is based on the properties and shape of the cross-correlation function, and is able to recover ~80% of all binaries with an orbital period of order 1 day. Systems with periods up to 1 yr are still within the detection reach. We have applied the method to 25,850 spectra of the RAVE second data release and found 123 double-lined binary candidates, only eight of which are already marked as binaries in the SIMBAD database. Among the candidates, there are seven that show spectral features consistent with the RS CVn type (solar type with active chromosphere) and seven that might be of W UMa type (over-contact binaries). One star, HD 101167, seems to be a triple system composed of three nearly identical G-type dwarfs. The tested classification method could also be applicable to the data of the upcoming Gaia mission.2010AJ....140..184Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/140/184CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toIII/265 : RAVE 3rd data release (Siebert+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/140/184https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/140/184http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/140/184https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/140/184https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/140/184http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/140/184GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/140/184/table1 (SB2 candidate spectra with solutions)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/140/184/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/140/184/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/140/184/table1?GETtext/xml+votable180.050000true0.39312-45.92950.005555555555555556Cone search capability for table J/AJ/140/184/table2 (Peculiar and low S/N SB2 candidate spectra)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/140/184/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/140/184/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/140/184/table2?GETtext/xml+votable180.050000true1.20621-21.698360.0055555555555555566/16631 16976 17003 17138 17246 17424 17426 17545 17550 17684 18471 18742 20656 21520 24597 24635 24636 24645 24695 24719 24746 25056 25270 25380 25451 25768 26129 26655 26818 26841 27056 29112 32848 32987 32990 33105 33107 33177 33256 33515 33557 33650 33672 33917 33949 33986 34009 34111 34132 34161 34184 34254 34345 34348 34679 34864 35026 35045 35085 35088 35108 35264 35451 35464 35494 35741 36650 36737 36791 36798 37546 38917 38950 41677 42391 43753 43771 43775 43848 43945 44004 44200 44426 44637 44675 44678 44716 44745 45006 45231 45242 45253 45285 45286 45292 45295 45650 45907 45925 45998 46084 46100 46239 46272 46298 46339 46407 46805 46806 46913 46946 47486 47487 48426 48672 48692 48699 48761 48837 48853 48860 48920 48981https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/140/184?format=asciiOpticaldefaultJ/AJ/140/184/table1SB2 candidate spectra with solutionsSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
