Spectroscopic companions

HD 24040 is of the sub-stellar companion (HD 24040 b ) orbits, for a period of 3400 d and a mass was determined from at least 4 times Jupiter's mass using the radial velocity method. It could thus act in the companion to an exoplanet. The semi-major axis would be about 8 astronomical units, the eccentricity be about 0,068. The companion is treated as a potential gas planet because of its high mass.
