The obliquity and atmosphere of the hot Jupiter WASP-122b (KELT-14b) with ESPRESSO: An aligned orbit and no sign of atomic or molecular absorption

M. Stangret, E. Palle, E. Esparza-Borges +21

Thanks to their short orbital periods and hot extended atmospheres, hot Jupiters are ideal candidates for atmosphere studies with high-resolution spectroscopy. New stable spectrogr…

Redshifted Sodium Transient near Exoplanet Transit

Apurva V. Oza, Julia V. Seidel, H. Jens Hoeijmakers +21

Neutral sodium (Na I) is an alkali metal with a favorable absorption cross section such that tenuous gases are easily illuminated at select transiting exoplanet systems. We examine…

ESPRESSO reveals blueshifted neutral iron emission lines on the dayside of WASP-76 b

A. R. Costa Silva, O. D. S. Demangeon, N. C. Santos +34

Ultra hot Jupiters (gas giants, Teq>2000 K) are intriguing exoplanets due to their extreme atmospheres. Their torrid daysides can be characterised using ground-based high-resolutio…

Atmospheric characterisation and tighter constraints on the orbital misalignment of WASP-94 A b with HARPS

E. Ahrer, J. V. Seidel, L. Doyle +10

We present high spectral resolution observations of the hot Jupiter WASP-94 A b using the HARPS instrument on ESO's 3.6m telescope in La Silla, Chile. We probed for Na absorption i…
