Stellar models require a convective step-overshoot of 1.2 to match the observed k2 in HD 152248, showing that standard models produce insufficient core-to-envelope density contrast in massive stars.

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.
New obliquity measurements for two Neptunes update the sample distribution to favor aligned systems plus a random component, resembling that of more massive planets and implying shared dynamical origins.
