cds-question@unistra.frmultiple-starsradial-velocityMost current radial velocity planet search programs have concentrated on stars of one solar mass. Our knowledge on the frequency of giant planets and brown dwarf companions to more massive stars is thus rather limited. In the case of solar-like stars, the frequency of short-period brown dwarf companions and very massive planets seems to be low. Aims. Here we present evidence for a substellar companion to 30 Ari B, an F-star of 1.16+/-0.04M_{sun}_ that is a member of a hierarchical triple system. The companion was detected by means of precise radial velocity measurements using the 2-m Alfred-Jensch telescope and its echelle spectrograph. An iodine absorption cell provided the wavelength reference for precise stellar radial velocity measurements.2009A&A...507.1659Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/507/1659CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/507/1659https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/507/1659http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/507/1659https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/507/1659https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/507/1659http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/507/1659GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/507/1659/rv30arbRadial velocities of 30 Ari B (table3 in the paper)recnoRecord number assigned by the VizieR team.
