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.
