cds-question@unistra.frradial-velocityspectroscopic-binary-starsIn previous works we reported the detection of a brown-dwarf companion orbiting the faint stellar component of the visual binary HD41004. This had been achieved by applying the multi-order TwO-Dimensional CORrelation (TODCOR) algorithm to CORALIE spectra. A long-term trend of the primary component had also been detected. In this paper we report on follow-up observations that seem to unravel the nature of this long-term trend. The new measurements are consistent with the presence of a 2.5M_J_ planet in an eccentric orbit around HD41004A. Thus, HD41004 is a unique hierarchical system where we have a brown-dwarf that accompanies the faint M-component, and a planet that orbits the brighter K-component.2004A&A...426..695Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/426/695CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/404/775 : Radial velocities of HD 41004A/B (Zucker+, 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/426/695https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/426/695http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/426/695https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/426/695https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/426/695http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/426/695GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/A+A/426/695/table2The radial velocities of HD41004A and HD41004BrecnoRecord number assigned by the VizieR team.
