The PEPSI Exoplanet Transit Survey (PETS) IV: Assessing the atmospheric chemistry of KELT-20b
Sydney Petz, Marshall C. Johnson, Anusha Pai Asnodkar +11
Most ultra hot Jupiters (UHJs) show evidence of temperature inversions, in which temperature increases with altitude over a range of pressures. Temperature inversions can occur whe…
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…
Retrieval of the dayside atmosphere of WASP-43b with CRIRES+
F. Lesjak, L. Nortmann, F. Yan +15
Accurately estimating the C/O ratio of hot Jupiter atmospheres is a promising pathway towards understanding planet formation and migration, as well as the formation of clouds and t…
Determination of small-scale magnetic fields on Sun-like stars in the near-infrared using CRIRES
A. Hahlin, O. Kochukhov, A. D. Rains +18
We aim to characterise the small-scale magnetic fields for a sample of 16 Sun-like stars and investigate the capabilities of the newly upgraded near-infrared (NIR) instrument CRIRE…
Exploring the stellar surface phenomena of WASP-52 and HAT-P-30 with ESPRESSO
H. M. Cegla, N. Roguet-Kern, M. Lendl +21
We analyse spectroscopic and photometric transits of the hot Jupiters WASP-52b and HAT-P30b obtained with ESPRESSO, Eulercam and NGTS for both targets, and additional TESS data for…
The PEPSI Exoplanet Transit Survey. III: The detection of FeI, CrI and TiI in the atmosphere of MASCARA-1 b through high-resolution emission spectroscopy
G. Scandariato, F. Borsa, A. S. Bonomo +19
Hot giant planets like MASCARA-1 b are expected to have thermally inverted atmospheres, that makes them perfect laboratory for the atmospheric characterization through high-resolut…
Solar center-to-limb variation in Rossiter-McLaughlin and exoplanet transmission spectroscopy
Ansgar Reiners, Fei Yan, Momo Ellwarth +2
Line profiles from spatially unresolved stellar observations consist of a superposition of local line profiles that result from observing the stellar atmosphere under specific view…
The CARMENES search for exoplanets around M dwarfs. Guaranteed time observations Data Release 1 (2016-2020)
I. Ribas, A. Reiners, M. Zechmeister +102
The CARMENES instrument was conceived to deliver high-accuracy radial velocity (RV) measurements with long-term stability to search for temperate rocky planets around a sample of n…
CRIRES+ detection of CO emissions lines and temperature inversions on the dayside of WASP-18b and WASP-76b
F. Yan, L. Nortmann, A. Reiners +21
The dayside atmospheres of ultra-hot Jupiters (UHJs) are predicted to possess temperature inversion layers with extremely high temperatures at high altitudes. We observed the daysi…
