cds-question@unistra.frspectroscopic-binary-starsradial-velocityRecent and on-going large ground-based multi-object spectroscopic surveys allow to significantly increase the sample of spectroscopic binaries to get insight into their statistical properties. We investigate the repeated spectral observations of the Gaia-ESO Survey (GES) internal data release 5 to identify and characterize spectroscopic binaries with one visible component (SB1) in fields covering the discs, the bulge, the CoRot fields, and stellar clusters and associations. A statistical chi2-test is performed on spectra of the iDR5 sub-sample of approximately 43500 stars characterized by at least 2 observations and a S/N>3. Our sample of RV variables is cleaned from contamination by pulsation/convection-induced variables using Gaia DR2 parallaxes and photometry. Monte-Carlo simulations using the SB9 catalogue of spectroscopic orbits allow to estimate our detection efficiency and to correct the SB1 rate to evaluate the GES SB1 binary fraction and its dependence with effective temperature and metallicity. We find 641 (resp., 803) FGK SB1 candidates at the 5 sigma (resp., 3 sigma) level. The orbital-period distribution is estimated from the RV standard-deviation distribution and reveals that the detected SB1 probe binaries with log(P[d]) < 4. We estimate the global GES SB1 fraction to be in the range 7-14% with a typical uncertainty of 4%. The GES SB1 frequency decreases with metallicity at a rate of -9+/-3%/dex in the metallicity range -2.7<FeH<+0.6. This anticorrelation is obtained with a confidence level higher than 93% on a homogeneous sample covering spectral types FGK and a large range of metallicities. When the present-day mass function is accounted for, this rate turns to 4+/-2%/dex with a confidence level higher than 88%. In addition we provide the variation of the SB1 fraction with metallicity separately for F, G, and K spectral types, as well as for dwarf and giant primaries.2020A&A...635A.155Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/635/A155CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/608/A95 : GES: multi-line spectroscopic binary candidates (Merle+, 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/635/A155https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/635/A155http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/635/A155https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/635/A155https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/635/A155http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/635/A155GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/635/A155/table3 (Catalogue of SB1 candidates with a confidence level at 5 sigma (set 1))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/635/A155/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/635/A155/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/635/A155/table3?GETtext/xml+votable180.050000true0.3467917-59.94477780.005555555555555556Cone search capability for table J/A+A/635/A155/table4 (Extension of SB1 candidates with a confidence level at 3 that makes set 2 along with table 3)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/635/A155/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/635/A155/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/635/A155/table4?GETtext/xml+votable180.050000true0.060875-54.86633330.0055555555555555565/11008 6/12405 16397 17300 17302 17374 17379 17382 17405 17714 17748 17768 17826-17827 18017 18088 18621 18639 18645 18677 18710 18724 18743 18834 18974 19025 19091-19092 20562 21017 21557 21594-21595 21778 21784 21801 21837 21839 21850 21864 21866 21912-21913 21929 22078-22079 22102 22945 22947 23123 23126 23204 25010 25074 25247 25262-25263 25281 25316 25320 25326 25346-25347 25445 25487 25498 25645 25688 25727 25763 25766 25830 25880 25882 26112 26692 26803 27172 27235 28720 28722 28746 28770 28778 28782 28970 30215 30292-30293 30295 30301 30464 30466-30467 30472 30906 31115 31236 31268 31272-31273 31332 31334 33253 33257 33321 33330 33499 33626 33633 33635 33641 33661 33702 33751 33771 33813 33818 33854 33894-33895 33927 33933 33953 33988 33995 34007 34018 34027 34035 34078 34093 34128 34216 34318 34348 34387 34434 34469 34494 34513 34864 34922 34944 34986 34999 35005 35022 35031 35051 35085 35160 35176 35219 35240 35344 35346 35356 35358 35361 35456 35534 35537 36794 37294 37933 37938 38240 38252 38316 38363 38366 38490-38491 38512 38684 38692 38694 39163 39332 39503 39584 39592 40349 40370 40392 40445 40641 40644 40667 40681 40818 40832 40881 40883 41507 41522 42177 42324-42325 42327 42340 42555 42649 42654 42663 42668 42670 43317 43371 43377 43389 43410-43411 43416 43419 43480 43506 43593 43611 43692 43710 43726 43748 43776 43794-43795 43806-43807 44077 44082-44083 44392 44507 44514 44516 44627 44630 44648 44686 44708 44756 44758 44835 44888-44889 45011 45527 45543 45546 45567 45781 45785 45788 45852 45865 45868 45887 45912 45925-45926 45976-45977 45990 46037-46039 46064 46128 46143 46179 46203 46225 46232 46246 46274 46285 46306 46315 46357 46366 46368-46369 46436 46617 46659 47125 47319 47344 47416 47418 47490 47644 47647 47661 47673-47675 47679 47720 47748-47750 47753 47759 47763-47764 47780-47781 47809 47812 48596 48598 48911 49151https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/635/A155?format=asciidefaultJ/A+A/635/A155/table3Catalogue of SB1 candidates with a confidence level at 5 sigma (set 1)recnoRecord number assigned by the VizieR team.
