Five new very low mass binaries
G. Montagnier, D. Segransan, J. -L. Beuzit +12
We report the discovery of companions to 5 nearby late M dwarfs (>M5), LHS1901, LHS4009, LHS6167, LP869-26 and WT460, and we confirm that the recently discovered mid-T brown dwarf…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) III. Atmospheric structure of the misaligned ultra-hot Jupiter WASP-121b
V. Bourrier, D. Ehrenreich, M. Lendl +21
Ultra-hot Jupiters offer interesting prospects for expanding our theories on dynamical evolution and the properties of extremely irradiated atmospheres. In this context, we present…
Radial-Velocity Fitting Challenge. II. First results of the analysis of the data set
X. Dumusque, F. Borsa, M. Damasso +21
Radial-velocity (RV) signals induce RV variations an order of magnitude larger than the signal created by the orbit of Earth-twins, thus preventing their detection. The goal of thi…
SPHERE: the exoplanet imager for the Very Large Telescope
J. -L. Beuzit, A. Vigan, D. Mouillet +108
Observations of circumstellar environments to look for the direct signal of exoplanets and the scattered light from disks has significant instrumental implications. In the past 15…
WASP-36b: A new transiting planet around a metal-poor G-dwarf, and an investigation into analyses based on a single transit light curve
A. M. S. Smith, D. R. Anderson, A. Collier Cameron +16
We report the discovery, from WASP and CORALIE, of a transiting exoplanet in a 1.54-d orbit. The host star, WASP-36, is a magnitude V = 12.7, metal-poor G2 dwarf (Teff = 5959 \pm 1…
A Window on Exoplanet Dynamical Histories: Rossiter-McLaughlin Observations of WASP-13b and WASP-32b
R. D. Brothwell, C. A. Watson, G. Hebrard +42
We present Rossiter-McLaughlin observations of WASP-13b and WASP-32b and determine the sky-projected angle between the normal of the planetary orbit and the stellar rotation axis (…
