Spitzer images resolve the debris disk around γ Ophiuchi at both 24 and 70 μm. The resolved images suggest a disk radius of ~520 AU at 70 μm and ≳ 260 AU at 24 μm. The images, along with a consistent fit to the spectral energy distribution of the disk from 20 to 350 μm, show that the primary disk structure is inclined by ~50° from the plane of the sky at a position angle of 55° ± 2°. Among a group of 12 debris disks that have similar host star spectral types, ages, and infrared fractional…

Observations of debris disks allow for the study of planetary systems, even where planets have not been detected. However, debris disks are often only characterized by unresolved infrared excesses

The architectures of debris disks encode the history of planet formation in these systems. Studies of debris disks via their spectral energy distributions (SEDs) have found infrared excesses arising
