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.

Spectral synthesis confirms β PsA is nearly pole-on (i≈4.75°) with rapid rotation (Ω/Ωcrit≈0.93), gravity darkening, and true luminosity 26.2 L⊙.
The HAges catalog compiles published asteroseismic and gyrochronological ages for 659 HWO target stars, finding that only ~5% have asteroseismic ages and ~20% have gyrochronal ages.
