Descrizione
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 research involving spin-orbit obliquities, such as the leading formation mechanism of hot-Jupiters, the role of migration in shaping the Neptune desert, ridge and savanna, and the role of obliquity excitation in the early stages of planet formation.
