An ESPRESSO view of HD 189733 system. Broadband transmission spectrum, differential rotation, and system architecture
E. Cristo, E. Esparza Borges, N. C. Santos +25
The development of state-of-the-art spectrographs has ushered in a new era in the detection and characterization of exoplanetary systems. Our objective is to utilize the high-resol…
On the Impact of ENSO Cycles and Climate Change on Telescope Sites in Northern Chile
Julia Victoria Seidel, Angel Otarola, Valentina Théron
The Atacama desert stands as the most arid, non-polar, region on Earth and has accommodated a considerable portion of the world's ground-based astronomical observatories for an ext…
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…
Effects of the Hunga Tonga-Hunga Ha'apai Volcanic Eruption on Observations at Paranal Observatory
Robert J. De Rosa, Angel Otarola, Thomas Szeifert +8
The Hunga Tonga-Hunga Ha'apai volcano erupted on 15 January 2022 with an energy equivalent to around 61 megatons of TNT. The explosion was bigger than any other volcanic eruption s…
Detection of a high-velocity sodium feature on the ultra-hot Jupiter WASP-121 b
J. V. Seidel, F. Borsa, L. Pino +19
Ultra-hot Jupiters, with their high equilibrium temperatures and resolved spectral lines, have emerged as a perfect testbed for new analysis techniques in the study of exoplanet at…
Hot Exoplanet Atmospheres Resolved with Transit Spectroscopy (HEARTS) VIII. Nondetection of sodium in the atmosphere of the aligned planet KELT-10b
M. Steiner, O. Attia, D. Ehrenreich +17
We searched for potential atmospheric species in KELT-10b, focusing on sodium doublet lines (Na i; 589 nm) and the Balmer alpha line (H ; 656 nm) in the transmission spectrum. F…
The hot Neptune WASP-166 b with ESPRESSO III: A blue-shifted tentative water signal constrains the presence of clouds
M. Lafarga, M. Brogi, S. Gandhi +8
With high-resolution spectroscopy we can study exoplanet atmospheres and learn about their chemical composition, temperature profiles, and presence of clouds and winds, mainly in h…
DREAM I. Orbital architecture orrery
V. Bourrier, O. Attia, M. Mallonn +28
The distribution of close-in exoplanets is shaped by a complex interplay between atmospheric and dynamical processes. The Desert-Rim Exoplanets Atmosphere and Migration (DREAM) pro…
