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…
Detection of sodium in the atmosphere of WASP-69b
N. Casasayas-Barris, E. Palle, G. Nowak +3
Transit spectroscopy is one of the most commonly used methods to characterize exoplanets atmospheres. From the ground, these observations are very challenging due to the terrestria…
K2-114b and K2-115b: Two Transiting Warm Jupiters
Avi Shporer, George Zhou, Benjamin J. Fulton +22
We report the first results from a search for transiting warm Jupiter exoplanets - gas giant planets receiving stellar irradiation below about erg s cm, equiva…
The GTC exoplanet transit spectroscopy survey VIII. Flat transmission spectrum for the warm gas giant WASP-80
Hannu Parviainen, Enric Palle, Guo Chen +7
We set out to study the atmosphere of WASP-80b, a warm inflated gas giant with an equilibrium temperature of 800~K, using ground-based transmission spectroscopy covering the…
The HARPS search for southern extra-solar planets XLII. A system of Earth-mass planets around the nearby M dwarf YZ Ceti
N. Astudillo-Defru, R. F. Díaz, X. Bonfils +13
Exoplanet surveys have shown that systems with multiple low-mass planets on compact orbits are common. Except for few cases, however, the masses of these planets are generally unkn…
Characterization of the K2-18 multi-planetary system with HARPS: A habitable zone super-Earth and discovery of a second, warm super-Earth on a non-coplanar orbit
R. Cloutier, N. Astudillo-Defru, R. Doyon +16
The bright M dwarf K2-18 at 34 pc is known to host a transiting super-Earth-sized planet orbiting within the star's habitable zone; K2-18b. Given the superlative nature of this sys…
The GTC exoplanet transit spectroscopy survey. VII. An optical transmission spectrum of WASP-48b
F. Murgas, E. Pallé, H. Parviainen +5
We obtained long-slit optical spectroscopy of one transit of WASP-48b with the Optical System for Imaging and low-Intermediate-Resolution Integrated Spectroscopy (OSIRIS) spectrogr…
MASCARA-2 b: A hot Jupiter transiting the A-star HD185603
G. J. J. Talens, A. B. Justesen, S. Albrecht +13
In this paper we present MASCARA-2 b, a hot Jupiter transiting the A2 star HD 185603. Since early 2015, MASCARA has taken more than 1.6 million flux measurements of the s…
A feature-rich transmission spectrum for WASP-127b
E. Palle, G. Chen, J. Prieto-Arranz +8
WASP-127b is one of the lowest density planets discovered to date. With a sub-Saturn mass () and super-Jupiter radius (),…
A temperate rocky super-Earth transiting a nearby cool star
Jason A. Dittmann, Jonathan M. Irwin, David Charbonneau +21
M dwarf stars, which have masses less than 60 per cent that of the Sun, make up 75 per cent of the population of the stars in the Galaxy [1]. The atmospheres of orbiting Earth-size…
The GTC exoplanet transit spectroscopy survey. VII. Detection of sodium in WASP-52b's cloudy atmosphere
G. Chen, E. Palle, L. Nortmann +3
We report the first detection of sodium absorption in the atmosphere of the hot Jupiter WASP-52b. We observed one transit of WASP-52b with the low-resolution Optical System for Ima…
The GTC exoplanet transit spectroscopy survey. VI. A spectrally-resolved Rayleigh scattering slope in GJ 3470b
G. Chen, E. W. Guenther, E. Palle +5
Aims. As a sub-Uranus-mass low-density planet, GJ 3470b has been found to show a flat featureless transmission spectrum in the infrared and a tentative Rayleigh scattering slope in…
The HARPS search for southern extra-solar planets XLI. A dozen planets around the M dwarfs GJ 3138, GJ 3323, GJ 273, GJ 628, and GJ 3293
N. Astudillo-Defru, T. Forveille, X. Bonfils +10
Context. Low mass stars are currently the best targets for searches for rocky planets in the habitable zone of their host star. Over the last 13 years, precise radial velocities me…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) I. Detection of hot neutral sodium at high altitudes on WASP-49b
A. Wyttenbach, C. Lovis, D. Ehrenreich +13
High-resolution optical spectroscopy during the transit of HD 189733b, a prototypical hot Jupiter, allowed the resolution of the Na I D sodium lines in the planet, giving access to…
