High-precision multi-wavelength eclipse photometry of the ultra-hot gas giant exoplanet WASP-103 b
L. Delrez, N. Madhusudhan, M. Lendl +14
We present sixteen occultation and three transit light curves for the ultra-short period hot Jupiter WASP-103 b, in addition to five new radial velocity measurements. We combine th…
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…
Temporal evolution of the high-energy irradiation and water content of TRAPPIST-1 exoplanets
V. Bourrier, J. de Wit, E. Bolmont +13
The ultracool dwarf star TRAPPIST-1 hosts seven Earth-size transiting planets, some of which could harbour liquid water on their surfaces. UV observations are essential to measure…
The structure of Chariklo's rings from stellar occultations
D. Bérard, B. Sicardy, J. I. B. Camargo +79
Two narrow and dense rings (called C1R and C2R) were discovered around the Centaur object (10199) Chariklo during a stellar occultation observed on 2013 June 3. Following this disc…
Study of the plutino object (208996) 2003 AZ84 from stellar occultations: size, shape and topographic features
A. Dias-Oliveira, B. Sicardy, J. L. Ortiz +60
We present results derived from four stellar occultations by the plutino object (208996) 2003~AZ, detected at January 8, 2011 (single-chord event), February 3, 2012 (multi-c…
The 67P/Churyumov-Gerasimenko observation campaign in support of the Rosetta mission
C. Snodgrass, M. F. A'Hearn, F. Aceituno +112
We present a summary of the campaign of remote observations that supported the European Space Agency's Rosetta mission. Telescopes across the globe (and in space) followed comet 67…
3D shape of asteroid (6)~Hebe from VLT/SPHERE imaging: Implications for the origin of ordinary H chondrites
M. Marsset, B. Carry, C. Dumas +15
Context. The high-angular-resolution capability of the new-generation ground-based adaptive-optics camera SPHERE at ESO VLT allows us to assess, for the very first time, the crater…
WASP-167b/KELT-13b: Joint discovery of a hot Jupiter transiting a rapidly-rotating F1V star
L. Y. Temple, C. Hellier, M. D. Albrow +46
We report the joint WASP/KELT discovery of WASP-167b/KELT-13b, a transiting hot Jupiter with a 2.02-d orbit around a = 10.5, F1V star with [Fe/H] = 0.1 0.1. The 1.5 R$_{\…
Probing the atmosphere of a sub-Jovian planet orbiting a cool dwarf
Elyar Sedaghati, Henri. M. J. Boffin, Laetitia Delrez +4
We derive the 0.01 m binned transmission spectrum, between 0.74 and 1.0 m, of WASP-80b from low resolution spectra obtained with the FORS2 instrument attached to ESO's Very L…
Seven temperate terrestrial planets around the nearby ultracool dwarf star TRAPPIST-1
Michael Gillon, Amaury H. M. J. Triaud, Brice-Olivier Demory +27
One focus of modern astronomy is to detect temperate terrestrial exoplanets well-suited for atmospheric characterisation. A milestone was recently achieved with the detection of th…
A seven-planet resonant chain in TRAPPIST-1
Rodrigo Luger, Marko Sestovic, Ethan Kruse +30
The TRAPPIST-1 system is the first transiting planet system found orbiting an ultra-cool dwarf star. At least seven planets similar to Earth in radius and in mass were previously f…
Reconnaissance of the TRAPPIST-1 exoplanet system in the Lyman- line
V. Bourrier, D. Ehrenreich, P. J. Wheatley +7
The TRAPPIST-1 system offers the opportunity to characterize terrestrial, potentially habitable planets orbiting a nearby ultracool dwarf star. We performed a four-orbit reconnaiss…
Searching For Rapid Orbital Decay of WASP-18b
Ashlee N. Wilkins, Laetitia Delrez, Adrian J. Barker +4
The WASP-18 system, with its massive and extremely close-in planet, WASP-18b (M = 10.3M, a = 0.02 AU, P = 22.6 hours), is one of the best known exoplanet laboratories t…
The discoveries of WASP-91b, WASP-105b and WASP-107b: two warm Jupiters and a planet in the transition region between ice giants and gas giants
D. R. Anderson, A. Collier Cameron, L. Delrez +17
We report the discoveries of three transiting exoplanets. WASP-91b is a warm Jupiter (1.34 , 1.03 ) in a 2.8-day orbit around a metal-rich K3 star. WASP-1…
