Analytic thin disks and rings in a class of nonasymptotically flat static spacetimes

Ruijing Tang, Shokoufe Faraji

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 show that the external quadrupolar distortion leaves a clear imprint on both orbital dynamics and accretion structure. We further find that the outer edge of the radiating region is closely tied to the transition between radiation pressure and gas pressure dominance.

C2weakest assumption

The local solution remains self-consistent over a physically meaningful radial domain, and the chosen exact vacuum spacetime accurately represents a slightly deformed compact object immersed in an external quadrupolar field.

C3one line summary

External quadrupolar distortion imprints on orbital dynamics and accretion structure in thin disks around deformed compact objects, with the radiating region's outer edge tied to the radiation-to-gas pressure transition.
