Formation of ultra-short-period planets by obliquity-driven tidal runaway
Small, rocky planets have been found orbiting in extreme proximity to their host stars,
sometimes down to only∼ 2 stellar radii. These ultra-short-period planets (USPs) likely did …

High-eccentricity Migration with Disk-induced Spin–Orbit Misalignment: A Preference for Perpendicular Hot Jupiters
High-eccentricity migration is a likely formation mechanism for many observed hot Jupiters,
particularly those with a large misalignment between the stellar spin axis and orbital angular …

Tilting Uranus via the migration of an ancient satellite
Context. The 98° obliquity of Uranus is commonly attributed to giant impacts that occurred at
the end of the planetary formation. This picture, however, is not devoid of weaknesses. Aims …
