141. Caratterizzazione delle atmosfere degli esopianeti: metodi, risultati e prospettive future

Guilluy, Gloria (Istituto Nazionale di Astrofisica (INAF))

A trent’anni dalla scoperta del primo pianeta attorno a una stella simile al Sole, l’esoplanetologia è passata da una fase pionieristica di scoperta a una scienza di caratterizzazione. Con oltre 6000 esopianeti attualmente confermati, è emersa un’inaspettata varietà di architetture planetarie, spesso prive di analoghi nel Sistema Solare. In questo contesto, lo studio delle atmosfere...

155. Spin-orbit alignment in planetary systems

Dr. Mantovan, Giacomo (Università degli studi di Padova (UniPd); Istituto Nazionale di Astrofisica (INAF))

Measuring spin-orbit obliquities via the Rossiter-McLaughlin effect is crucial for understanding how planets form and migrate. Different mechanisms are expected to leave different signatures in the obliquity; scattering encounters tend to randomise orbital alignments, whereas disc-planet interactions tend to preserve orbital coplanarity. In this talk, I will present hot topics in exoplanet...

199. KELT‑9b as a preview of the ELT era: probing 3D dynamics and thermochemical regimes with GIARPS

di Paola, Alessia (Istituto Nazionale di Astrofisica (INAF) - OATo)

High-resolution spectroscopy has evolved over the past decade into a key technique for exoplanet atmospheric characterization, enabling detailed constraints on chemical composition, thermal structure, and atmospheric dynamics. Ultra-Hot Jupiters (UHJs), with their extreme irradiation and temperatures, offer unique laboratories for exploring atmospheric physics under conditions far beyond those...

196. From Neptunes to Earths: Implications from Multi-Resolution Atmospheric Characterization of WASP-107b for Future ELT Observations of Terrestrial Exoplanet

Amadori, Francesco (Istituto Nazionale di Astrofisica (INAF))

06/05/26, 10:00

The atmospheric characterization of Neptune-mass exoplanets serves as a crucial stepping stone toward understanding smaller, potentially habitable worlds. This study presents a comprehensive multi-resolution analysis of WASP-107b, a warm super-Neptune with an extended atmosphere ideal for transmission spectroscopy, using the novel GUIBRUSH® framework that combines high-resolution ground-based...
