Radial velocities of HD 41004A/B
Listed in IVOA Registry (Virtual Observatory)
In previous works we reported the detection of a brown-dwarf companion orbiting the faint stellar component of the visual binary HD41004.
Description
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.
