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…

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…

Connection between planetary He I 10830 Ã absorption and extreme-ultraviolet emission of planet-host stars
J. Sanz-Forcada, M. López-Puertas, M. Lampón +13
Context. The detection of the He I 10830 A triplet in exoplanet atmospheres has opened a new window for probing planetary properties, including atmospheric escape. Unlike Lyman alp…
