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.
