Abstract:
The characterization of four new transiting extrasolar planets is
presented here. KOI-188b and KOI-195b are bloated hot Saturns, with
orbital periods of 3.8 and 3.2-days, and masses of 0.25 and
0.34MJup, respectively. They are located in the low-mass range of
known transiting, giant planets. KOI-192b has a similar mass
(0.29MJup) but a longer orbital period of 10.3 days. This places it
in a domain where only few planets are known. KOI-830b, finally, with
a mass of 1.27MJup and a period of 3.5-days, is a typical hot
Jupiter. The four planets have radii of 0.98, 1.09, 1.2, and
1.08RJup, respectively. We detected no significant eccentricity in
any of the systems, while the accuracy of our data does not rule out
possible moderate eccentricities. The four objects were first
identified by the Kepler Team as promising candidates from photometry
of the Kepler satellite. We establish here their planetary nature
thanks to the radial velocity follow-up we secured with the HARPS-N
spectrograph at the Telescopio Nazionale Galileo. The combined
analyses of the whole datasets allow us to fully characterize the four
planetary systems. These new objects increase the number of
well-characterized exoplanets for statistics, and provide new targets
for individual follow-up studies. The pre-screening we performed with
the SOPHIE spectrograph at the Observatoire de Haute-Provence as part
of that study also allowed us to conclude that a fifth candidate,
KOI-219.01, is not a planet but is a false positive.
