cds-question@unistra.frLong-period brown dwarf companions detected in radial velocity surveys are important targets for direct imaging and astrometry to calibrate the mass-luminosity relation of substellar objects. Through a 20-year radial velocity monitoring of solar-type stars that began with ELODIE and was extended with SOPHIE spectrographs, giant exoplanets and brown dwarfs with orbital periods longer than ten years are discovered. We report the detection of five new potential brown dwarfs with minimum masses between 32 and 83M_Jup_ orbiting solar-type stars with periods longer than ten years. An upper mass limit of these companions is provided using astrometric Hipparcos data, high-angular resolution imaging made with PUEO, and a deep analysis of the cross-correlation function of the main stellar spectra to search for blend effects or faint secondary components. These objects double the number of known brown dwarf companions with orbital periods longer than ten years and reinforce the conclusion that the occurrence of such objects increases with orbital separation. With a projected separation larger than 100mas, all these brown dwarf candidates are appropriate targets for high-contrast and high angular resolution imaging.2016A&A...585A..46Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/585/A46CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/505/853 : HD16760 radial velocity curve (Bouchy+, 2009)J/A+A/513/A69 : HD9446 radial velocity curve (Hebrard+, 2010)J/A+A/523/A88 : A Jupiter-mass companion around HD 109246 (Boisse+, 2010)J/A+A/538/A113 : Radial velocities of eight stars (Diaz+, 2012)J/A+A/545/A55 : Radial velocities of 5 stars (Boisse+, 2012)J/A+A/563/A22 : Radial velocities of 3 new hot Jupiters (Moutou+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/585/A46https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/585/A46http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/585/A46https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/585/A46https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/585/A46http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/585/A46GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/585/A46/stars (Target characteristics, summary of observations and stellar parameters (tables 1 & 2 of the paper))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/585/A46/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/585/A46/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/585/A46/stars?GETtext/xml+votable180.050000true26.68725.9180.0055555555555555566/2077 2305 3313 4227 191563.322582951404819e-19 3.852589004194616e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/585/A46?format=asciiOpticaldefaultJ/A+A/585/A46/table5Radial velocities of HD 10844RVRadial velocitykm/sphys.veloc;pos.heliocentricdoublerecnoRecord number assigned by the VizieR team.
