Abstract:
Distinguishing classes within substellar objects and understanding
their formation and evolution need larger samples of substellar
companions such as exoplanets, brown dwarfs, and low-mass stars. In
this paper, we look for substellar companions using radial velocity
surveys of FGK stars with the SOPHIE spectrograph at the Observatoire
de Haute-Provence. We assign here the radial velocity variations of 27
stars to their orbital motion induced by low-mass companions. We also
constrained their plane-of-the-sky motion using HIPPARCOS and Gaia
Data Release 1 measurements, which constrain the true masses of some
of these companions. We report the detection and characterization of
six cool Jupiters, three brown dwarf candidates, and 16 low-mass
stellar companions. We additionally update the orbital parameters of
the low-mass star HD 8291 B, and we conclude that the radial velocity
variations of HD 204277 are likely due to stellar activity despite
resembling the signal of a giant planet. One of the new giant planets,
BD+631405 b, adds to the population of highly eccentric cool Jupiters,
and it is presently the most massive member. Two of the cool Jupiter
systems also exhibit signatures of an additional outer companion. The
orbital periods of the new companions span 30 days to 11.5 years,
their masses 0.72MJup to 0.61M☉, and their eccentricities 0.04
to 0.88. These discoveries probe the diversity of substellar objects
and low-mass stars, which will help constrain the models of their
formation and evolution.
Description:
We tabulated the radial velocity data obtained with the SOPHIE
spectrograph at Observatoire de Haute-Provence for the 27 targets
published in this article. This includes epochs, radial velocity,
uncertainty on radial velocity, with FWHM, and bisector spans for the
SOPHIE spectra.
