TL;DR: In this article, the spectral profiles of Na, K, and Li absorption in the atmosphere of the super-Neptune WASP-127b, at 4.1 σ, 5.0 σ, and 3.4 σ respectively, were obtained from the 10.4 m Gran Telescopio Canarias (GTC) and 2.5 m Nordic Optical Telescope (NOT).
Journal ArticleDOI
Detection of neutral atomic species in the ultra-hot Jupiter WASP-121b
TL;DR: In this article, high-resolution optical spectra obtained during transits of WASP-121~b were used to detect atmospheric absorption from H$\alpha$ in the planet with a transit depth of $1.87\pm0.11\%.
Journal ArticleDOI
On Degeneracies in Retrievals of Exoplanetary Transmission Spectra
Luis Welbanks,Nikku Madhusudhan +1 more
TL;DR: In this article, a combination of detailed atmospheric retrievals and a range of model assumptions, focusing on H$_2$-rich atmospheres, is used to estimate atmospheric properties of exoplanets from transmission spectra.
Journal ArticleDOI
An optical transmission spectrum of the ultra-hot Jupiter WASP-33b. First indication of AlO in an exoplanet
C. von Essen,Matthias Mallonn,Luis Welbanks,Nikku Madhusudhan,A. Pinhas,Hervé Bouy,P. Weis Hansen +6 more
TL;DR: In this article, the authors used the OSIRIS spectrograph to characterize the atmosphere of the ultra-hot Jupiter WASP-33b using two primary transits taken 18 orbits apart.
