Titanium chemistry of WASP-121 b with ESPRESSO in 4-UT mode

B. Prinoth, J. V. Seidel, H. J. Hoeijmakers +15

Transit spectroscopy usually relies on the integration of one or several transits to achieve the S/N necessary to resolve spectral features. Consequently, high-S/N observations of…

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…

Secrets in the shadow: High precision stellar abundances of fast-rotating A-type exoplanet host stars through transit spectroscopy

M. B. Lam, H. J. Hoeijmakers, B. Prinoth +1

Context. The spectra of fast-rotating A-type stars have strongly broadened absorption lines. This effect causes blending of the absorption lines, hindering the measurement of the a…

Hot Rocks Survey II: The thermal emission of TOI-1468 b reveals a hot bare rock

E. A. Meier Valdés, B. -O. Demory, H. Diamond-Lowe +17

Terrestrial exoplanets orbiting nearby small, cool stars known as M dwarfs are well suited for atmospheric characterisation. Given the strong XUV irradiation from M dwarf host star…

Detection of atmospheric species and dynamics in the bloated hot Jupiter WASP-172~b with ESPRESSO

J. V. Seidel, B. Prinoth, E. Knudstrup +3

The population of strongly irradiated Jupiter-sized planets has no equivalent in the Solar System. It is characterised by strongly bloated atmospheres and atmospheric large-scale h…

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,…
