Mercedes Lopez-Morales, Raphaelle D. Haywood, Jeffrey L. Coughlin +36
HD 179070, aka Kepler-21, is a V = 8.25 F6IV star and the brightest exoplanet host discovered by Kepler. An early detailed analysis by Howell et al. (2012) of the first thirteen mo…
The Orbit and Mass of the Third Planet in the Kepler-56 System
Oderah Justin Otor, Benjamin T. Montet, John Asher Johnson +20
While the vast majority of multiple-planet systems have their orbital angular momentum axes aligned with the spin axis of their host star, Kepler-56 is an exception: its two transi…

Lars A. Buchhave, Courtney D. Dressing, Xavier Dumusque +35
Kepler-20 is a solar-type star (V = 12.5) hosting a compact system of five transiting planets, all packed within the orbital distance of Mercury in our own Solar System. A transiti…
WASP-86b and WASP-102b: super-dense versus bloated planets
F. Faedi, Y. Gómez Maqueo Chew, D. Pollacco +38
We report the discovery of two transiting planetary systems: a super dense, sub-Jupiter mass planet WASP-86b (\mpl\ = 0.82 0.06 \mj, \rpl\ = 0.63 0.01 \rj), and a bloat…
The mass of planet GJ676A b from ground-based astrometry: A planetary system with two mature gas giants suitable for direct imaging
J. Sahlmann, P. F. Lazorenko, D. Ségransan +10
GJ676A is an M0 dwarf hosting both gas-giant and super-Earth-type planets discovered with radial-velocity measurements. Using FORS2/VLT, we obtained position measurements of the st…
Discovery of WASP-113b and WASP-114b, two inflated hot-Jupiters with contrasting densities

We present the discovery and characterisation of the exoplanets WASP-113b and WASP-114b by the WASP survey, {\it SOPHIE} and {\it CORALIE}. The planetary nature of the systems was…
WASP-92b, WASP-93b and WASP-118b: Three new transiting close-in giant planets
K. L. Hay, A. Collier-Cameron, A. P. Doyle +36
We present the discovery of three new transiting giant planets, first detected with the WASP telescopes, and establish their planetary nature with follow up spectroscopy and ground…
From dense hot Jupiter to low-density Neptune: The discovery of WASP-127b, WASP-136b and WASP-138b
K. W. F. Lam, F. Faedi, D. J. A. Brown +38
We report three newly discovered exoplanets from the SuperWASP survey. WASP-127b is a heavily inflated super-Neptune of mass 0.18 +/- 0.02 M_J and radius 1.37 +/- 0.04 R_J. This is…
Probing TRAPPIST-1-like systems with K2
Brice-Olivier Demory, Didier Queloz, Yann Alibert +2
The search for small planets orbiting late M dwarfs holds the promise of detecting Earth-size planets for which their atmospheres could be characterised within the next decade. The…
A combined transmission spectrum of the Earth-sized exoplanets TRAPPIST-1 b and c
Julien de Wit, Hannah R. Wakeford, Michael Gillon +9
Three Earth-sized exoplanets were recently discovered close to the habitable zone of the nearby ultracool dwarf star TRAPPIST-1. The nature of these planets has yet to be determine…
Temperate Earth-sized planets transiting a nearby ultracool dwarf star
Michael Gillon, Emmanuel Jehin, Susan M. Lederer +12
Star-like objects with effective temperatures of less than 2,700 kelvin are referred to as ultracool dwarfs. This heterogeneous group includes stars of extremely low mass as well a…
The SOPHIE search for northern extrasolar planets. XI. Three new companions and an orbit update: Giant planets in the habitable zone
R. F. Díaz, J. Rey, O. Demangeon +25
We report the discovery of three new substellar companions to solar-type stars, HD191806, HD214823, and HD221585, based on radial velocity measurements obtained at the Haute-Proven…
A map of the large day-night temperature gradient of a super-Earth exoplanet
Brice-Olivier Demory, Michael Gillon, Julien de Wit +11
Over the past decade, observations of giant exoplanets (Jupiter-size) have provided key insights into their atmospheres, but the properties of lower-mass exoplanets (sub-Neptune) r…
