A temperate exo-Earth around a quiet M dwarf at 3.4 parsecs
Xavier Bonfils, Nicola Astudillo-Defru, Rodrigo Díaz +12
The combination of high-contrast imaging and high-dispersion spectroscopy, which has successfully been used to detect the atmosphere of a giant planet, is one of the most promising…
The discovery of WASP-151b, WASP-153b, WASP-156b: Insights on giant planet migration and the upper boundary of the Neptunian desert
Olivier. D. S. Demangeon, F. Faedi, G. Hébrard +31
To investigate the origin of the features discovered in the exoplanet population, the knowledge of exoplanets' mass and radius with a good precision is essential. In this paper, we…
The EBLM Project IV. Spectroscopic orbits of over 100 eclipsing M dwarfs masquerading as transiting hot-Jupiters
Amaury H. M. J. Triaud, David V. Martin, Damien Ségransan +15
We present 2271 radial velocity measurements taken on 118 single-line binary stars, taken over eight years with the CORALIE spectrograph. The binaries consist of F/G/K primaries an…
The EBLM project III. A Saturn-size low-mass star at the hydrogen-burning limit
Alexander von Boetticher, Amaury H. M. J. Triaud, Didier Queloz +19
We report the discovery of an eclipsing binary system with mass-ratio q 0.07. After identifying a periodic photometric signal received by WASP, we obtained CORALIE spectrosc…
Gaia Data Release 1. Testing the parallaxes with local Cepheids and RR Lyrae stars
Gaia Collaboration, G. Clementini, L. Eyer +588
Parallaxes for 331 classical Cepheids, 31 Type II Cepheids and 364 RR Lyrae stars in common between Gaia and the Hipparcos and Tycho-2 catalogues are published in Gaia Data Release…
The SOPHIE search for northern extrasolar planets - XII. Three giant planets suitable for astrometric mass determination with Gaia
Javiera Rey, Guillaume Hébrard, François Bouchy +22
We present new radial velocity measurements for three low-metallicity solar-like stars observed with the SOPHIE spectrograph and its predecessor ELODIE, both installed at the 193 c…
