cds-question@unistra.frmultiple-starsm-starsradial-velocityWe observed stars with variable radial velocities to determine their spectroscopic orbits. Velocities of 132 targets taken over a time span reaching 30 years are presented. They were measured with the correlation radial velocity spectrometers (1913 velocities) and the new VUES echelle spectrograph (632 velocities), with typical accuracy of 0.5 and 0.2km/s, respectively. We derived spectroscopic orbits of 57 stars (including 53 first-time orbits), mostly nearby dwarfs of spectral types K and M. Their periods range from 2.2 days to 14 years, some of those are Hipparcos astrometric binaries. Comments on individual objects are provided. Many stars belong to hierarchical systems containing three or more components, including 20 new hierarchies resulting from this project. The preliminary orbit of the young star HIP 47110B has a large eccentricity e=0.47 despite short period of 4.4d; it could be still circularizing. Our results enrich the data on nearby stars and contribute toa better definition of the multiplicity statistics.2019A&A...626A..31Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/626/A31CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/235/6 : Updated multiple star catalog (MSC) May 2018 (Tokovinin, 2018)J/A+A/596/A116 : Radial velocities of K-M dwarfs (Sperauskas+, 2016)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/626/A31https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/626/A31http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/626/A31https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/626/A31https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/626/A31http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/626/A31GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/626/A31/table1 (Object list)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/626/A31/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/626/A31/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/626/A31/table1?GETtext/xml+votable180.050000true0.304958313.97508330.0055555555555555566/158 826 940 1121 1230 1252 1262 1506 1547 1698 2248 2505 3088 3210 3291 3303 3510 3863 4396 4468 4810 5024 5166 5476 5491 5677 5684 5767 5880 5992 6391 6565 6619 7303 7875 7950 8766 8794 8856 9231 9280 9730 9745 9776 10130 10156 10225 10247 10306 10467 10771 10785 11034 11118 11126 11225 11292 11322 12332 13156 13196 13214 13512 13559 13693 13742 13943 14058 14377 15253 15422 15703 15952 16034 16275 16993 17255 17893 18480 19663 19778 19919 20107 20131-20132 20429 20896 20957 21375 22140 22570 23272 23401 23660 23770 24300 24356 25003 25037 26042 26428 26460 26492 26563 26716 26834 27691 27872 28018 28080 28244 28492 28618 30198 32089 32147 32652 40664 40795 40893 48975https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/626/A31?format=asciidefaultJ/A+A/626/A31/table1Object listSimbadNameSimbad column added by the CDSmeta.idcharrecnoRecord number assigned by the VizieR team.
