cds-question@unistra.frgiant-starsradial-velocityWe present radial-velocity (RV) measurements for the K giant nu Oph (=HIP 88048, HD 163917, HR 6698), which reveal two brown dwarf companions with a period ratio close to 6:1. For our orbital analysis we use 150 precise RV measurements taken at the Lick Observatory between 2000 and 2011, and we combine them with RV data for this star available in the literature. Using a stellar mass of M=2.7M_{sun}_ for nu Oph and applying a self-consistent N-body model we estimate the minimum dynamical companion masses to be m_1_sini~22.2M_Jup_ and m_2_sini~24.7M_Jup_, with orbital periods P_1_~530d and P_2_~3185d.2019A&A...624A..18Qhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/624/A18CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/475/1003 : Stellar parameters of G and K giant stars (Hekker+, 2007)J/A+A/574/A116 : G and K giant stars stellar parameters (Reffert+, 2015)J/A+A/595/A55 : Radial velocity data of HD 59686 A (Ortiz+, 2016)J/A+A/616/A33 : Stellar parameters of 372 giant stars (Stock+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/624/A18https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/624/A18http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/624/A18https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/624/A18https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/624/A18http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/624/A18GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/624/A18/tablea1Radial velocities and errorsrecnoRecord number assigned by the VizieR team.
