cds-question@unistra.frspectroscopic-binary-starsradial-velocityWe present the results of our second radial velocity (RV) monitoring campaign, carried out with the Echelle spectrograph FLECHAS at the University Observatory Jena in the course of the Grosschwabhausen binary survey between December 2016 and June 2018. The aim of this project is to obtain precise RV measurements for spectroscopic binary stars in order to redetermine, verify, improve, and constrain their Keplerian orbital solutions. In this paper, we describe the observations, data reduction, and analysis and present the results of this project. In total, we have taken 721 RV measurements of 11 stars and derived well-determined orbital solutions for nine systems (seven single- and two double-lined spectroscopic binaries) with periods in the range between 2 and 70 days. In addition, we could rule out the orbital solutions for the previously classified spectroscopic binary systems HIP 107136 and HIP 107533, whose radial velocities are found to be constant on the km/s-level over a span of time of more than 500 days. In the case of HIP 2225, a significant change of its systematic velocity is detected between our individual observing epochs, indicating the presence of an additional companion, which is located on a wider orbit in this system.2020AN....341...99Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AN/341/99CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/sb9 : SB9: 9th Catalogue of Spectroscopic Binary OrbitsJ/AN/338/671 : RV measurements of eight spectroscopic binaries (Bischoff+ 2017)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AN/341/99https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AN/341/99http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AN/341/99https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AN/341/99https://vizier.iucaa.in/viz-bin/votable?-source=J/AN/341/99http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AN/341/99GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AN/341/99/table1 (Properties of the observed targets)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AN/341/99/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AN/341/99/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AN/341/99/table1?GETtext/xml+votable180.050000true325.595666741.07702780.0055555555555555566/1385 1855 2762 7075 9836 10096 13752 13973 14055 14074 14733https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AN/341/99?format=asciidefaultJ/AN/341/99/table1Properties of the observed targetsrecnoRecord number assigned by the VizieR team.
