A broad exploration of climate and observability of close-in rocky exoplanets: applications to Ross 128 b
Mathilde Houelle, Houelle Mathilde, Emeline Bolmont +12
VLT/RISTRETTO, ELT/ANDES and ELT/PCS will soon enable atmospheric characterization of non-transiting, small rocky exoplanets orbiting closer than the inner edge of the Habitable Zo…
DD4AO control law for RISTRETTO: robustness, real-time performance, and on-sky validation with PAPYRUS
Isaac Dinis, Muskan Schinde, Nicolas Blind +11
The paper presents the DD4AO frequency‑domain, data‑driven adaptive optics controller, its implementation in the RISTRETTO instrument, and on‑sky validation with the PAPYRUS system…
The breaking of cold traps and onset of titanium in ultra-hot Jupiter atmospheres: WASP-189b in context
Stefan Pelletier, Romain Allart, Valentina Vaulato +56
Condensates are ubiquitous to all Solar System planets with significant (10mbar) atmospheres. The same is true for most exoplanets with characterised atmospheres, with even ultr…
Resolving protoplanetary H-alpha emission with the high-resolution spectrograph RISTRETTO
J. W. Blackman, C. Mordasini, G. -D. Marleau +4
Thousands of exoplanets have been discovered to date, but only a handful of them are young planets in the latter stages of their formation. H-alpha emission is a strong tracer of t…
Active moons in our Solar System and beyond -- Io, Europa, Enceladus, Triton, and exomoons
Caroline Haslebacher, Emeline Bolmont, Marco Cilibrasi +19
The outgassing signatures of Io, Europa, Enceladus, Triton, and Io-like exomoons are the focus of this review chapter. The rocky volcanic world of Io is unique in our Solar System,…
Recent development in high-precision high-fidelity spectrographs for exoplanet research and characterization
François Bouchy, Francesco Pepe, Xavier Dumusque +3
High-precision high-fidelity spectrographs are the most powerful instruments for exoplanets detection and characterization. The sub-m/s radial-velocity precision, required to detec…
