HD207897 b: A dense sub-Neptune transiting a nearby and bright K-type star
N. Heidari, I. Boisse, J. Orell-Mique +90
We present the discovery and characterization of a transiting sub-Neptune orbiting with a 16.20 day period around a nearby (28 pc) and bright(V=8.37) K0V star HD207897 (TOI-1611).…
K2-30b and K2-34b: two inflated hot-Jupiters around Solar-type stars
J. Lillo-Box, O. Demangeon, A. Santerne +23
We report the discovery of the two hot-Jupiters K2-30b and K2-34b. The two planets were detected transiting their main-sequence star with periods 4.099 and 2.996 days…
The SOPHIE search for northern extrasolar planets XIII. Two planets around M-dwarfs Gl617A and Gl96
M. J. Hobson, R. F. DÃaz, X. Delfosse +32
We report the detection of two exoplanets and a further tentative candidate around the M-dwarf stars Gl96 and Gl617A, based on radial velocity measurements obtained with the SOPHIE…
The SOPHIE search for northern extrasolar planets VIII. A warm Neptune orbiting HD164595
B. Courcol, F. Bouchy, F. Pepe +23
High-precision radial velocity surveys explore the population of low-mass exoplanets orbiting bright stars. This allows accurately deriving their orbital parameters such as their o…
SOPHIE velocimetry of Kepler transit candidates XVIII. Radial velocity confirmation, absolute masses and radii, and origin of the Kepler-419 multiplanetary system
J. M. Almenara, R. F. DÃaz, G. Hébrard +14
Kepler-419 is a planetary system discovered by the Kepler photometry which is known to harbour two massive giant planets: [...] Here we present new radial velocity (RV) measurement…
The SOPHIE search for northern extrasolar planets IX. Populating the brown dwarf desert
P. A. Wilson, G. Hébrard, N. C. Santos +20
Radial velocity planet search surveys of nearby Solar-type stars have shown a strong deficit of brown dwarf companions within . There is presently no comprehens…
