ADC_Keywords: Stars, double and multiple ; Planets ; Radial velocities Keywords: techniques: radial velocities - stars: general - brown dwarfs Abstract: Radial velocity planet search surveys of nearby solar-type stars have shown a strong scarcity of brown dwarf companions within ∼5AU. There is presently no comprehensive explanation for this lack of brown dwarf companions; therefore, increasing the sample of such objects is crucial to understand their formation and evolution. Based on precise radial velocities obtained using the SOPHIE spectrograph at Observatoire de Haute-Provence we characterise the orbital parameters of 15 companions to solar-type stars and constrain their true mass using astrometric data from the Hipparcos space mission. The nine companions not shown to be stellar in nature have minimum masses ranging from ∼13 to 70M_Jup , and are well distributed across the planet/brown dwarf mass regime, making them an important contribution to the known population of massive companions around solar-type stars. We characterise six companions as stellar in nature with masses ranging from a minimum mass of 76±4MJup to a mass of 0.35±0.03M. The orbital parameters of two previously known substellar candidates are improved. Description: The catalogue is composed of 15 radial velocity timeseries, one for each target listed above. The radial velocities were obtained with the SOPHIE spectrograph at the 1.93-m telescope at the Observatoire de Haute-Provence. Addtional information for each star include the estimated uncertainty in the radial velocity.
