Atmospheric composition of WASP-85Ab with ESPRESSO/VLT observations

Zewen Jiang, Wei Wang, Guo Chen +9

Transit spectroscopy is the most frequently used technique to reveal the atmospheric properties of exoplanets, while that at high resolution has the advantage to resolve the small…

The PEPSI Exoplanet Transit Survey (PETS) I: Investigating the presence of a silicate atmosphere on the super-Earth 55 Cnc e

Engin Keles, Matthias Mallonn, Daniel Kitzmann +26

The study of exoplanets and especially their atmospheres can reveal key insights on their evolution by identifying specific atmospheric species. For such atmospheric investigations…

Evidence for TiO in the atmosphere of the hot Jupiter HAT-P-65 b

Guo Chen, Enric Palle, Hannu Parviainen +2

We present the low-resolution transmission spectra of the puffy hot Jupiter HAT-P-65b (0.53 M, 1.89 R, K), based on two transits…

Indications for very high metallicity and absence of methane for the eccentric exo-Saturn WASP-117b

Ludmila Carone, Paul Mollière, Yifan Zhou +12

We investigate the atmospheric composition of the long period ( 10 days), eccentric exo-Saturn WASP-117b. WASP-117b could be in atmospheric temperature and chemistry…

A giant exoplanet orbiting a very low-mass star challenges planet formation models

J. C. Morales, A. J. Mustill, I. Ribas +179

Statistical analyses from exoplanet surveys around low-mass stars indicate that super-Earth and Neptune-mass planets are more frequent than gas giants around such stars, in agreeme…

Ground-based detection of an extended helium atmosphere in the Saturn-mass exoplanet WASP-69b

Lisa Nortmann, Enric Pallé, Michael Salz +25

Hot gas giant exoplanets can lose part of their atmosphere due to strong stellar irradiation, affecting their physical and chemical evolution. Studies of atmospheric escape from ex…
