Detection of the hydrogen Balmer lines in the ultra-hot Jupiter WASP-33b
F. Yan, A. Wyttenbach, N. Casasayas-Barris +24
Ultra-hot Jupiters (UHJs) are highly irradiated giant exoplanets with extremely high day-side temperatures, which lead to thermal dissociation of most of the molecular species. It…
The widest broadband transmission spectrum (0.38-1.71 m) of HD 189733b from ground-based chromatic Rossiter-McLaughlin observations
M. Oshagh, F. F. Bauer, M. Lafarga +22
Multiband photometric transit observations (spectro-photometric) have been used mostly so far to retrieve broadband transmission spectra of transiting exoplanets in order to study…
Discriminating between hazy and clear hot-Jupiter atmospheres with CARMENES
A. Sánchez-López, M. López-Puertas, I. A. G. Snellen +20
Context: Relatively large radii of some hot Jupiters observed in the ultraviolet (UV) and blue-optical are generally interpreted to be due to Rayleigh scattering by high-altitude h…
Obliquity measurement and atmospheric characterization of the WASP-74 planetary system
R. Luque, N. Casasayas-Barris, H. Parviainen +27
We present new transit observations of the hot Jupiter WASP-74 b ( 1860 K) using the high-resolution spectrograph HARPS-N and the multi-colour simultaneous imag…
A temperature inversion with atomic iron in the ultra-hot dayside atmosphere of WASP-189b
F. Yan, E. Pallé, A. Reiners +6
Temperature inversion layers are predicted to be present in ultra-hot giant planet atmospheres. Although such inversion layers have recently been observed in several ultra-hot Jupi…
Transmission spectroscopy and Rossiter-McLaughlin measurements of the young Neptune orbiting AU Mic
E. Palle, M Oshagh, N. Casasayas-Barris +8
AU Mic~b is a Neptune size planet on a 8.47-day orbit around the nearest pre-main sequence (20 Myr) star to the Sun, the bright (V=8.81) M dwarf AU Mic. The planet was prelim…
A He I upper atmosphere around the warm Neptune GJ 3470b
E. Palle, L. Nortmann, N. Casasayas-Barris +24
High resolution transit spectroscopy has proven to be a reliable technique for the characterization of the chemical composition of exoplanet atmospheres. Taking advantage of the br…
Detection of Fe I and Fe II in the atmosphere of MASCARA-2b using a cross-correlation method
M. Stangret, N. Casasayas-Barris, E. Pallé +3
Ultra-hot Jupiters are gas giants planets whose dayside temperature, due to the strong irradiation received from the host star, is greater than 2200 K. These kind of objects are pe…
The CARMENES search for exoplanets around M dwarfs. Two planets on the opposite sides of the radius gap transiting the nearby M dwarf LTT 3780
G. Nowak, R. Luque, H. Parviainen +97
We present the discovery and characterisation of two transiting planets observed by the Transiting Exoplanet Survey Satellite (TESS) orbiting the nearby (d ~ 22 pc), bright (J ~ 9…
Is there NaI in the atmosphere of HD 209458b? Effect of the centre-to-limb variation and Rossiter-McLaughlin effect in transmission spectroscopy studies
N. Casasayas-Barris, E. Palle, F. Yan +22
HD 209458b was the first transiting planet discovered, and the first for which an atmosphere, in particular NaI, was detected. With time, it has become one of the most frequently s…
Detection of Na, K, and H absorption in the atmosphere of WASP-52b using ESPRESSO
G. Chen, N. Casasayas-Barris, E. Palle +5
WASP-52b is a low density hot Jupiter orbiting a moderately active K2V star. Previous low-resolution studies have revealed a cloudy atmosphere and found atomic Na above the cloud d…
