Simulations show that von Zeipel-Lidov-Kozai migration from inclined companions produces misaligned short-period hot Jupiters while coplanar high-eccentricity migration preserves alignment at longer periods.
Scattering between close-in super-Earths and secularly perturbed cold planets can launch some planets into free-floating orbits.
Simulations indicate EKL interactions excite TTV phases and disrupt resonances in a significant fraction of near-resonant super-Earth systems over 16 Myr.
Sub-Neptunes around metal-rich stars have a 42.6% conditional probability of cold Jupiters versus 14.5% for super-Earths, showing a metallicity-dependent correlation absent in the latter.
Simulations using occurrence rates rank HWO ExEP stars by probability of hosting a temperate terrestrial planet or moon, reaching up to 50% for some systems.
Giant planet multiplicity is low, with 10.6% and 15.8% of Sun-like stars hosting at least one giant planet within 10 au across the two surveys, mostly as singles, inconsistent with scattering models.
Observational analysis of 43 systems finds no significant overall correlation between gas giant occurrence and inner small planet properties but reports hints of a trend in metal-rich systems favoring lower-density planets with similar core masses.
