Abstract:
We present new radial velocity measurements of eight stars that were
secured with the spectrograph SOPHIE at the 193cm telescope of the
Haute-Provence Observatory. The measurements allow detecting and
characterizing new giant extrasolar planets. The host stars are dwarfs
of spectral types between F5 and K0 and magnitudes of between 6.7 and
9.6; the planets have minimum masses Mpsini of between 0.4 to
3.8MJup and orbitalperiods of several days to several months. The
data allow only single planets to be discovered around the first six
stars (HD 143105, HIP 109600, HD 35759, HIP 109384,
HD 220842, and HD 12484), but one of them shows the signature of
an additional substellar companion in the system. The seventh star,
HIP 65407, allows the discovery of two giant planets that orbit just
outside the 12:5 resonance in weak mutual interaction. The last star,
HD 141399, was already known to host a four-planet system; our
additional data and analyses allow new constraints to be set on it. We
present Keplerian orbits of all systems, together with dynamical
analyses of the two multi-planet systems. HD 143105 is one of the
brightest stars known to host a hot Jupiter, which could allow
numerous follow-up studies to be conducted even though this is not a
transiting system. The giant planets HIP 109600b, HIP 109384b, and
HD 141399c are located in the habitable zone of their host star.
Description:
We observed the eight stars with SOPHIE at the OHP 1.93m telescope.
SOPHIE is a cross-dispersed, environmentally stabilized echelle
spectrograph dedicated to high-precision radial velocity measurements.
Observations were secured in fast-reading mode of the detector and in
high-resolution mode of the spectrograph, allowing a resolution power
of λ/Δλ=75000 to be reached. Depending on the
star, the spectra were obtained over time spans of two to eight years.
Their typical exposure times are a few minutes to reach a
signal-to-noise ratio per pixel at 550nm of around 50. The final
dataset presented here represents nearly 600 exposures for a total
integration time exceeding 60 hours on the sky.
