JWST observations at 15 and 25.5 μm reveal a smooth, radially broad debris disk around γ Ophiuchi extending to 250 au, interpreted as a steady-state collisional cascade from a wide planetesimal belt with possible low-eccentricity planetary perturbation.

A 2D Monte Carlo dust evolution simulation shows that a planet-induced pressure bump reproduces the observed compositions and formation ages of carbonaceous chondrites, implying formation in a single long-lived dust trap outside Jupiter's orbit.
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.
