The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We find that while larger gas masses lead to more efficient outward radial drift, the resulting radial offset strongly depends on the optical depth of the disk, as the drift efficiency directly competes with the particles' collisional lifetime.

C2weakest assumption

The simulations rely on assumed gas surface density profiles, collisional lifetimes, and optical depth values tuned to match typical debris disk conditions; if these are inaccurate for the ARKS sample, the predicted offsets may not apply.

C3one line summary

Simulations demonstrate that gas-dust interactions produce radial offsets between micron and millimeter dust in gas-bearing debris disks, depending on gas mass, optical depth, and small-grain abundance.
