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…

A neural network approach to determining photometric metallicities of M-type dwarf stars

C. Duque-Arribas, H. M. Tabernero, D. Montes +2

M dwarfs are the most abundant stars in the Galaxy and serve as key targets for stellar and exoplanetary studies. It is particularly challenging to determine their metallicities be…

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…
