JWST/NIRISS reveals the water-rich "steam world" atmosphere of GJ 9827 d

Caroline Piaulet-Ghorayeb, Bjorn Benneke, Michael Radica +30

With sizable volatile envelopes but smaller radii than the solar system ice giants, sub-Neptunes have been revealed as one of the most common types of planet in the galaxy. While t…

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…

A sub-Earth-mass planet orbiting Barnard's star

J. I. Gonzalez Hernandez, A. Suarez Mascareno, A. M. Silva +37

Barnard's star is a primary target within the ESPRESSO guaranteed time observations (GTO) as it is the second closest neighbour to our Sun after the Centauri stellar system. We…

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…
