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…
An enhanced slope in the transmission spectrum of the hot Jupiter WASP-104b
G. Chen, E. Palle, H. Parviainen +25
We present the optical transmission spectrum of the hot Jupiter WASP-104b based on one transit observed by the blue and red channels of the DBSP spectrograph at the Palomar 200-inc…
A data-driven approach to constraining the atmospheric temperature structure of KELT-9b
L. Fossati, D. Shulyak, A. G. Sreejith +10
Context. Observationally constraining the atmospheric temperature-pressure (TP) profile of exoplanets is an important step forward for improving planetary atmosphere models, furthe…
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…
LBT transmission spectroscopy of HAT-P-12b: confirmation of a cloudy atmosphere with no significant alkali features
F. Yan, N. Espinoza, K. Molaverdikhani +10
The hot sub-Saturn-mass exoplanet HAT-P-12b is an ideal target for transmission spectroscopy because of its inflated radius. We observed one transit of the planet with the multi-ob…
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…
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…
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…
