cds-question@unistra.frspectroscopic-binary-starsradial-velocityThree of the six southern Clube Areas that were mainly observed at the European Southern Observatory and whose principal results are given in Paper XVI (Griffin & Cornell 2006, Cat. <J/MNRAS/371/1140>) are marginally observable from Haute-Provence. Additional measurements obtained on several observing runs there enabled orbits to be determined (in most cases rather poorly, owing to the paucity of data) for 30 of the newly discovered spectroscopic-binary systems; they are presented in this paper. One object, HD 33978, seems to be of such significance that special efforts have been made, largely by Drs J. Andersen and H. Lindgren, to obtain additional radial-velocity measurements. That system is shown to be a double-lined binary with a period of only 10.67d despite one of its components being a late-type giant. The giant star has a projected rotational velocity of almost 40km/s; it could be expected to exhibit RS CVn-type photometric variations, which have not yet been observed, in addition to the 'ellipsoidal variation', discovered by Hipparcos, which occasioned its designation as VV Lep.2006MNRAS.371.1159Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/371/1159CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/371/1140 : K0 stars radial velocities (Griffin+, 2006)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/371/1159https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/371/1159http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/371/1159https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/371/1159https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/371/1159http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/371/1159GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/371/1159/table1 (The 30 stars whose orbits are presented below)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/371/1159/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/371/1159/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/371/1159/table1?GETtext/xml+votable180.050000true153.7398953-22.22179280.0055555555555555566/21011 21014 21023 21040 21067 25116 25125 25130 25147 25154 25223 25260 25313 34684 34766 34790 34811 38870 40261 43884 43887 43902 43969 43971 43987 44024 44556 44568 44605 44684https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/371/1159?format=asciidefaultJ/MNRAS/371/1159/table1The 30 stars whose orbits are presented belowrecnoRecord number assigned by the VizieR team.
