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: No evidence of transits in TESS photometry
A. K. Stefanov, J. I. González Hernández, A. Suárez Mascareño +8
A sub-Earth-mass planet orbiting Barnard's star, designated as Barnard b, has been recently announced. At almost the same time, the first photometric data of Barnard's star by the…
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…
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,…
TESS and ESPRESSO discover a super-Earth and a mini-Neptune orbiting the K-dwarf TOI-238
A. Suárez Mascareño, V. M. Passegger, J. I. González Hernández +53
The number of super-Earth and mini-Neptune planet discoveries has increased significantly in the last two decades thanks to transit and radial velocity surveys. When it is possible…
The compact multi-planet system GJ 9827 revisited with ESPRESSO
V. M. Passegger, A. Suárez Mascareño, R. Allart +36
GJ 9827 is a bright, nearby K7V star orbited by two super-Earths and one mini-Neptune on close-in orbits. The system was first discovered using K2 data and then further characteriz…
Euclid preparation: XLVIII. The pre-launch Science Ground Segment simulation framework
Euclid Collaboration, S. Serrano, P. Hudelot +274
The European Space Agency's Euclid mission is one of the upcoming generation of large-scale cosmology surveys, which will map the large-scale structure in the Universe with unprece…
