Evidence of Sculpting by Stellar and Sub-stellar Companions in Debris Disks in the ScoCen
Abstract
We study the location and composition of the dust in debris disk systems in the Scorpius-Centaurus OB Association by modeling their Spitzer IRS infrared spectra features. Nearly all of our sources can be modeled as one or two belts of dust consisting of amorphous silicates. In those systems with stellar companions, there is evidence of disk truncation at the outer radius caused by the binary. No circumbinary debris disks are identified. We explore the possibility that the two-belt systems result from gaps carved out by unseen planets and constrain the location and masses of those planets based on how closely spaced those belts are.
