An extremely low-density and temperate giant exoplanet

A. Santerne, L. Malavolta, M. R. Kosiarek +68

Transiting extrasolar planets are key objects in the study of the formation, migration, and evolution of planetary systems. In particular, the exploration of the atmospheres of gia…

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…
