cds-question@unistra.frk-starsgiant-starsradial-velocityexoplanetsWe report the discovery of long-period radial velocity (RV) variations in six intermediate-mass K-giant stars using precise RV measurements. These discoveries are part of the Search for Exoplanets around Northern Circumpolar Stars (SENS) survey being conducted at the Bohyunsan Optical Astronomy Observatory. The nature of the RV variations was investigated by looking for photometric and line shape variations. We can find no variability with the RV period in these quantities and conclude that RV variations are most likely due to unseen sub-stellar companions. Orbital solutions for the six stars yield orbital periods in the range 418-1065 days and minimum masses in the range 1.9-8.5 M_J_. These properties are typical on planets around intermediate-mass stars. Our SENS survey so far has about an 8% confirmed planet occurrence rate, and it will provide better statistics on planets around giant stars when the survey is completed.2018AJ....156...64Jhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/156/64CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/430/165 : Radial velocities for 6691 K and M giants (Famaey+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/156/64https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/156/64http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/156/64https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/156/64https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/156/64http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/156/64GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/156/64/stars (List of stars)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/156/64/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/156/64/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/156/64/stars?GETtext/xml+votable180.050000true98.266666778.97952780.0055555555555555566/8022 8108 11964 11987 12117 16135https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/156/64?format=asciidefaultJ/AJ/156/64/table3RV measurementsrecnoRecord number assigned by the VizieR team.
