Homogeneous reanalysis of 145 single-star RM systems reveals mass-dependent e-λ trends: sub-Saturns eccentric and misaligned, Jupiters misaligned only when circular, and super-Jupiters aligned at all eccentricities.

A brown-dwarf companion's close pericenter in KELT-20 imposes dynamical limits that disfavor giant planet formation beyond the water-ice line.
TOI-201 has three planets whose co-transiting configuration will end in 200 years due to Kozai-Lidov oscillations driven by mutual inclinations.
Tentative evidence for a super-Jupiter at 15-100 AU or brown dwarf at 20-170 AU in 51 Pegasi from RV curvature, but the signal is likely driven by Lick/Hamilton instrument drift.
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.
