The CORALIE survey for southern extra-solar planets - XV. Discovery of two eccentric planets orbiting HD 4113 and HD 156846
We report the detection of two very eccentric planets orbiting HD 4113 and HD 156846 with the CORALIE Echelle spectrograph mounted on the 1.2-m Euler Swiss telescope at La Silla. The first planet, HDExpand

SOPHIE velocimetry of Kepler transit candidates - XII. KOI-1257 b: a highly eccentric three-month period transiting exoplanet
In this paper we report a new transiting warm giant planet: KOI-1257 b. It was first detected in photometry as a planet-candidate by the Kepler space telescope and then validated thanks to a radialExpand

Dissecting the Moth: discovery of an off-centered ring in the HD 61005 debris disk with high-resolution imaging
The debris disk known as “The Moth” is named after its unusually asymmetric surface brightness distribution. It is locat ed around the � 90 Myr old G8V star HD 61005 at 34.5 pc and has previouslyExpand

SOPHIE velocimetry of Kepler transit candidates XVI. Tomographic measurement of the low obliquity of KOI-12b, a warm Jupiter transiting a fast rotator
We present the detection and characterization of the transiting warm Jupiter KOI-12b, first identified with Kepler with an orbital period of 17.86 days. We combine the analysis of Kepler photometryExpand

Direct imaging of extra-solar planets in star forming regions - Lessons learned from a false positive around IM Lupi
Context. Most exoplanet imagers consist of ground-based adaptive optics coronagraphic cameras which are currently limited in contrast, sensitivity and astrometric precision, but advantageouslyExpand

Hot circumstellar material resolved around β Pic with VLTI/PIONIER
Aims. We aim at resolving the circumstellar environment around β Pic in the near-infrared in order to study the inner planetary system (<200 mas, i.e., ~4 AU). Methods. Precise interferometricExpand
