Scattering cold Jupiters disrupt inner mean-motion resonances via secular perturbations from their orbital history, driving resonance circulation in most 2:1 and 3:2 configurations and explaining the Kepler period ratio distribution.
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.
Planetesimal disks with 1-4% of the planetary mass disrupt resonant Neptune chains, triggering instabilities that scatter planets to ~0.1 au orbits and enable hot Neptune formation on 10-100 Myr timescales.
Two-stage GMM clustering of close-in exoplanets in dynamical feature space mapped to pebble-accretion models identifies sub-populations with distinct formation histories including earlier epochs for very-massive gas giants.
2D radiation-hydrodynamical simulations find accretion outbursts unstable to Rossby-wave instability, forming vortices that suppress planetesimal formation until post-burst quiescence.
N-body simulations show that 14 Herculis's orbital architecture requires primordial ejection of an additional massive planet.
An optimal Stokes number window of 0.01-0.03 allows streaming instability to form planetesimals and pebble accretion to build all three main planet classes, with cold gas giants needing the lowest turbulence and largest discs.
Reanalysis of 79 solar twins indicates the Sun's chemical peculiarity is largely explained by Galactic chemical evolution, with 2-6 candidates possibly showing planetary engulfment.
CHEOPS photometry improves radii for V1298 Tau b, c, and d, producing revised densities of 0.06-0.23 g cm^{-3} that indicate differential atmospheric evolution and no requirement for past dynamical excitation.
