Roche lobe overflow during gas giant destruction aligns stellar spins with orbits within tens of degrees regardless of starting conditions, offering an observable to differentiate this mechanism from high-eccentricity migration.
New 2025 transit timing for HIP 41378 f confirms large TTVs and is combined with prior data on planets d and e in an N-body model to update ephemerides and predict future transits.
Archival RV and astrometric data plus three-body simulations constrain an unseen outer perturber in the GJ 436 system to sub-Jovian masses at a_c ≳ 6.8 AU, supporting Kozai-Lidov migration as the source of the hot Neptune's polar eccentric orbit.

Observational and Dynamical Constraints on an Unseen Outer Perturber in the GJ 436 Hot Neptune System
Archival RV and astrometric data plus three-body simulations constrain an unseen outer perturber in the GJ 436 system to sub-Jovian masses at a_c ≳ 6.8 AU, supporting Kozai-Lidov migration as the source of the hot Neptune's polar eccentric orbit.
