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…
The atmospheric composition of the ultra-hot Jupiter WASP-178 b observed with ESPRESSO
Y. C. Damasceno, J. V. Seidel, B. Prinoth +25
We search for atmospheric constituents for the UHJ WASP-178 b with two ESPRESSO transits using the narrow-band and cross-correlation techniques, focusing on the detections of NaI,…
Unveiling the internal structure and formation history of the three planets transiting HIP 29442 (TOI-469) with CHEOPS
J. A. Egger, H. P. Osborn, D. Kubyshkina +91
Multiplanetary systems spanning the radius valley are ideal testing grounds for exploring the proposed explanations for the observed bimodality in the radius distribution of close-…
The Aligned Orbit of a Hot Jupiter around the M Dwarf TOI-4201
Tianjun Gan, Sharon X. Wang, Fei Dai +12
Measuring the obliquities of stars hosting giant planets may shed light on the dynamical history of planetary systems. Significant efforts have been made to measure the obliquities…
HIP 41378 observed by CHEOPS: Where is planet d?
S. Sulis, L. Borsato, S. Grouffal +84
HIP 41378 d is a long-period planet that has only been observed to transit twice, three years apart, with K2. According to stability considerations and a partial detection of the R…
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…
