Abstract:
The mass domain where massive extrasolar planets and brown dwarfs lie
is still poorly understood. Indeed, not even a clear dividing line
between massive planets and brown dwarfs has been established yet.
This is partly because these objects are very scarce in close orbits
around solar-type stars, the so-called brown dwarf desert. Owing to
this, it has proven difficult to set up a strong observational base
with which to compare models and theories of formation and evolution.
We search to increase the current sample of massive sub-stellar
objects with precise orbital parameters, and to constrain the true
mass of detected sub-stellar candidates
Description:
The catalogue is composed of eight 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, the bissector slope of
the cross-correlation function, the exposure time, and the
signal-to-noise ratio per pixel.
