Retrieving wind properties from the ultra-hot dayside of WASP-189b with CRIRES

F. Lesjak, L. Nortmann, D. Cont +12

The extreme temperature gradients from day- to nightside in the atmospheres of hot Jupiters generate fast winds in the form of equatorial jets or day-to-night flows. Observations o…

Exploring the ultra-hot Jupiter WASP-178b. Constraints on atmospheric chemistry and dynamics from a joint retrieval of VLT/CRIRES and space photometric data

D. Cont, L. Nortmann, F. Yan +14

Despite recent progress in the spectroscopic characterization of individual exoplanets, the atmospheres of key ultra-hot Jupiters (UHJs) still lack comprehensive investigations. Th…

Detection of Fe and Ti on the dayside of the ultrahot Jupiter MASCARA-1b with CARMENES

B. Guo, F. Yan, L. Nortmann +20

Ultrahot Jupiters are a type of gaseous exoplanet that orbit extremely close to their host star, resulting in significantly high equilibrium temperatures. In recent years, high-res…

The MOPYS project: A survey of 70 planets in search of extended He I and H atmospheres. No evidence of enhanced evaporation in young planets

J. Orell-Miquel, F. Murgas, E. Pallé +30

During the first Gyr of their life, exoplanet atmospheres suffer from different atmospheric escape phenomena that can strongly affect the shape and morphology of the exoplanet itse…
