Direct imaging over 11 years confirms β Pictoris d as a ~2.4 MJup, ~600 K bound companion at ~26 au, coplanar with b and c and consistent with sculpting the debris-disk inner edge.

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.
Secular perturbations from an inner planet create sharp, marching peaks and caustic discontinuities in a debris disk's azimuthally-averaged surface density, with radial locations following a predictable power-law pattern.
ALMA observed 3933 independent coordinates in nearby star-forming regions for disks and planet formation, analyzed by sky location, frequency coverage, exposure time, spectral lines, and angular resolution.
