Confirmation of an He I evaporating atmosphere around the 650-Myr-old sub-Neptune HD235088 b (TOI-1430 b) with CARMENES
J. Orell-Miquel, M. Lampón, M. López-Puertas +31
HD235088 (TOI-1430) is a young star known to host a sub-Neptune-sized planet candidate. We validated the planetary nature of HD235088 b with multiband photometry, refined its plane…
Characterisation of the upper atmospheres of HAT-P-32 b, WASP-69 b, GJ 1214 b, and WASP-76 b through their He I triplet absorption
M. Lampón, M. López-Puertas, J. Sanz-Forcada +14
Characterisation of atmospheres undergoing photo-evaporation is key to understanding the formation, evolution, and diversity of planets. However, only a few upper atmospheres that…
Atmospheric characterization of the ultra-hot Jupiter WASP-33b: Detection of Ti and V emission lines and retrieval of a broadened line profile
D. Cont, F. Yan, A. Reiners +17
Ultra-hot Jupiters are highly irradiated gas giant exoplanets on close-in orbits around their host stars. We analyzed high-resolution spectra from CARMENES, HARPS-N, and ESPaDOnS t…
Detection of Paschen absorption in the atmosphere of KELT-9 b: A new window into the atmospheres of ultra-hot Jupiters
A. Sánchez-López, L. Lin, I. A. G. Snellen +4
Hydrogen and helium transmission signals trace the upper atmospheres of hot gas-giant exoplanets, where the incoming stellar extreme ultraviolet and X-ray fluxes are deposited. Fur…
A tentative detection of He I in the atmosphere of GJ 1214b
J. Orell-Miquel, F. Murgas, E. Pallé +27
The $\ion{He}{I}$ 10833\, triplet is a powerful tool for characterising the upper atmosphere of exoplanets and tracing possible mass loss. Here, we analysed one transit of GJ\,1…
Detection of iron emission lines and a temperature inversion on the dayside of the ultra-hot Jupiter KELT-20b
F. Yan, A. Reiners, E. Pallé +25
Ultra-hot Jupiters (UHJs) are gas giants with very high equilibrium temperatures. In recent years, multiple chemical species, including various atoms and ions, have been discovered…
Silicon in the dayside atmospheres of two ultra-hot Jupiters
D. Cont, F. Yan, A. Reiners +22
Atmospheres of highly irradiated gas giant planets host a large variety of atomic and ionic species. Here we observe the thermal emission spectra of the two ultra-hot Jupiters WASP…
Moderately misaligned orbit of the warm sub-Saturn HD 332231 b
Elyar Sedaghati, Alejando Sánchez-López, Stefan Czesla +9
Measurements of exoplanetary orbital obliquity angles for different classes of planets are an essential tool in testing various planet formation theories. Measurements for those tr…
H and He I absorption in HAT-P-32 b observed with CARMENES -- Detection of Roche lobe overflow and mass loss
S. Czesla, M. Lampón, J. Sanz-Forcada +22
We analyze two high-resolution spectral transit time series of the hot Jupiter HAT-P-32 b obtained with the CARMENES spectrograph. Our new XMM-Newton X-ray observations of the syst…
Probing the atmosphere of WASP-69 b with low- and high-resolution transmission spectroscopy
S. Khalafinejad, K. Molaverdikhani, J. Blecic +31
Consideration of both low- and high-resolution transmission spectroscopy is key for obtaining a comprehensive picture of exoplanet atmospheres. In studies of transmission spectra,…
