The SOPHIE search for northern extrasolar planets -- XVII. A wealth of new objects: Six cool Jupiters, three brown dwarfs, and 16 low-mass binary stars
S. Dalal, F. Kiefer, G. Hébrard +30
Distinguishing classes within substellar objects and understanding their formation and evolution need larger samples of substellar companions such as exoplanets, brown dwarfs, and…
Irradiated ocean planets bridge super-Earth and sub-Neptune populations
Olivier Mousis, Magali Deleuil, Artyom Aguichine +5
Small planets (1--3.9 $\Rearth$) constitute more than half of the inventory of the 4000-plus exoplanets discovered so far. Smaller planets are sufficiently dense to be rocky,…
The SOPHIE search for northern extrasolar planets. XVI. HD 158259: A compact planetary system in a near-3:2 mean motion resonance chain
N. C. Hara, F. Bouchy, M. Stalport +32
Since 2011, the SOPHIE spectrograph has been used to search for Neptunes and super-Earths in the Northern Hemisphere. As part of this observational program, 290 radial velocity mea…
Exoplanet characterisation in the longest known resonant chain: the K2-138 system seen by HARPS
T. A. Lopez, S. C. C. Barros, A. Santerne +36
The detection of low-mass transiting exoplanets in multiple systems brings new constraints to planetary formation and evolution processes and challenges the current planet formatio…
The SOPHIE search for northern extrasolar planets. XIV. A temperate ( K) super-earth around the nearby star Gliese 411
R. F. Díaz, X. Delfosse, M. J. Hobson +33
Periodic radial velocity variations in the nearby M-dwarf star Gl411 are reported, based on measurements with the SOPHIE spectrograph. Current data do not allow us to distinguish b…
The SOPHIE search for northern extrasolar planets XV. A Warm Neptune around the M-dwarf Gl378
M. J. Hobson, X. Delfosse, N. Astudillo-Defru +31
We present the detection of a Warm Neptune orbiting the M-dwarf Gl378, using radial velocity measurements obtained with the SOPHIE spectrograph at the Observatoire de Haute-Provenc…
