What Sets the Radial Locations of Warm Debris Disks

摘要: The architectures of debris disks encode the history planet formation in these systems. Studies via their spectral energy distributions (SEDs) have found infrared excesses arising from cold dust, warm or a combination two. outer belts many systems been imaged, facilitating study great detail. Far less is known about components, including origin dust. regularity disk temperatures indicates an underlying structure that may be linked to water snow line. If dust generated collisions exo-asteroid belt, will likely trace location line primordial protoplanetary where planetesimal growth was enhanced. instead arises inward transport reservoir icy material farther out system, expected set by current We analyze SEDs large sample with components. find components single-component (those without detectable components) follow rather than line, so they arise belts. While locations two-component are also consistent there more diversity among systems, suggesting additional effects play role.
