Abstract:
While giant extrasolar planets have been studied for more than two
decades now, there are still some open questions as to their dominant
formation and migration processes, as well as to their atmospheric
evolution in different stellar environments. In this paper, we study
a sample of giant transiting exoplanets detected by the Kepler
telescope with orbital periods up to 400 days. We first defined a
sample of 129 giant-planet candidates that we followed up with the
SOPHIE spectrograph (OHP, France) in a 6-year radial velocity
campaign. This allowed us to unveil the nature of these candidates and
to measure a false-positive rate of 54.6±6.5% for giant-planet
candidates orbiting within 400 days of period. Based on a sample of
confirmed or likely planets, we then derived the occurrence rates of
giant planets in different ranges of orbital periods. The overall
occurrence rate of giant planets within 400 days is 4.6±0.6%. We
recovered, for the first time in the Kepler data, the different
populations of giant planets reported by radial velocity surveys.
Comparing these rates with other yields, we find that the occurrence
rate of giant planets is lower only for hot Jupiters but not for the
longer-period planets. We also derive a first measurement of the
occurrence rate of brown dwarfs in the brown-dwarf desert with a value
of 0.29±0.17%. Finally, we discuss the physical properties of the
giant planets in our sample. We confirm that giant planets receiving
moderate irradiation are not inflated, but we find that they are on
average smaller than predicted by formation and evolution models. In
this regime of low-irradiated giant planets, we find a possible
correlation between their bulk density and the iron abundance of the
host star, which needs more detections to be confirmed.
Description:
We observed the candidate sample with the SOPHIE spectrograph
mounted on the 1.93m telescope at the Observatoire de Haute-Provence
(France)
The observations were done as part of a large programme dedicated to
Kepler targets and funded by the French Programme of Planetology
from 2010 July 14 to 2015 July 15.
