A W-Net deep learning model detects asteroids in TESS data independently of trajectory by rotating training image cubes and using adaptive normalization for data scaling.
Sharp migration-rate gradients in protoplanetary disks quench resonant overstability when the dimensionless steepness parameter β exceeds the ratio of semi-major axis to eccentricity evolution timescales.
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.
A new wide-binary coordinate system in REBOUND's TRACE integrator produces qualitatively correct results for planet-planet scattering, stellar flybys, and ZLK oscillations where prior hybrid integrators fail, while matching IAS15 accuracy at up to 9x speed.
Numerical relativity simulations of hierarchical mergers in collapsar-disk geometry show eccentricity building to 0.6 and partially surviving (up to 0.1) to merger, offering a gravitational-wave signature for this formation scenario.
Close substellar companions suppress metal pollution in white dwarfs by a factor of 5.75 with 87% protection efficiency, backed by observations of 17 systems and N-body simulations.
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.
N-body simulations demonstrate that post-capture chaotic planet-planet interactions around pulsars can produce stable low-eccentricity orbits after ejections.
Simulations show stars at the edges of stellar streams are more likely to retain unperturbed planetary systems than stars near the stream center.
Viscous stirring via gravitational scattering produces lognormal inclination distributions that yield Lorentzian vertical density profiles, which relax to Gaussians after equipartition, enabling estimates of perturber masses in ARKS debris disks.
GPU-accelerated N-body simulations show that the common acceleration factor f distorts planetary chemical compositions and that terrestrial planets can form resonant chains without gas-driven orbital migration.
Comet Halley exhibits a precise 15:1 commensurability with a 1,151-year solar-system quasi-period, with Jupiter and Saturn providing coherent perturbation cancellation over that baseline.
