Spinning out of focus: The challenge of rotational line broadening in exoplanet reflection spectroscopy
T. O. Winterhalder, K. Molaverdikhani, D. Cont +17
Detecting light reflected off the dayside of an exoplanet in high-resolution spectroscopic data has proved to be a notoriously difficult endeavour. Despite several attempts, the fa…
Elemental abundance pattern and temperature inversion on the dayside of HAT-P-70b observed with CARMENES and PEPSI
B. Guo, F. Yan, Th. Henning +25
Ground-based high-resolution spectroscopy has identified various chemical species in the atmospheres of ultra-hot Jupiters, including neutral and ionized metals, providing key insi…
Revisiting the atmosphere of HAT-P-70b with CARMENES high-resolution transmission spectroscopy
Tianjun Gan, Jaume Orell-Miquel, Fei Yan +19
Owing to hot and inflated envelopes that facilitate atmospheric studies, ultra-hot Jupiters (UHJs) have attracted much attention. Significant progress has been achieved, from enlar…
Tighter constraints on the atmosphere of GJ 436 b from combined high-resolution CARMENES and CRIRES observations
A. Peláez-Torres, A. Sánchez-López, L. Nortmann +23
We aim to study the atmospheric properties of the warm Neptune GJ 436 b by combining a set of five transit events observed with the CARMENES spectrograph with one transit from CRIR…
Upper limits on atmospheric abundances of KELT-11b and WASP-69b from a retrieval approach
F. Lesjak, L. Nortmann, D. Cont +18
WASP-69b and KELT-11b are two low-density hot Jupiters, which are expected to show strong atmospheric features in their transmission spectra. Such features offer valuable insights…
A planetary system with a sub-Neptune planet in the habitable zone of TOI-2093
J. Sanz-Forcada, E. González-Álvarez, M. R. Zapatero Osorio +33
Aims. We aim to confirm and measure the mass of the transiting planet candidate around the K5V star TOI-2093, previously announced by the Transiting Exoplanet Survey Satellite (TES…
Retrieving day- and nightside atmospheric properties of the ultra-hot Jupiter TOI-2109b. Detection of Fe and CO emission lines and evidence for inefficient heat transport
D. Cont, L. Nortmann, F. Lesjak +32
The ultra-hot Jupiter (UHJ) TOI-2109b marks the lower edge of the equilibrium temperature gap between 3500 K and 4500 K, an unexplored thermal regime that separates KELT-9b, the ho…
Revisiting the dynamical masses of the transiting planets in the young AU Mic system: Potential AU Mic b inflation at 20 Myr
M. Mallorquín, V. J. S. Béjar, N. Lodieu +26
Understanding planet formation is important in the context of the origin of planetary systems in general and of the Solar System in particular, as well as to predict the likelihood…
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…
The elusive atmosphere of WASP-12 b / High-resolution transmission spectroscopy with CARMENES
S. Czesla, M. Lampón, D. Cont +19
To date, the hot Jupiter WASP-12 b has been the only planet with confirmed orbital decay. The late F-type host star has been hypothesized to be surrounded by a large structure of c…
