The Neptunian ridge as a natural outcome of high-eccentricity tidal migration

A. Castro-Gonz\'alez, A. C. M. Correia, D. Ehrenreich, D. J. Armstrong, M. Lendl, V. Bourrier

High-eccentricity tidal migration explains the Neptunian ridge as a natural clustering of survivors beyond the tidal disruption limit.

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

High-eccentricity tidal migration thus provides a self-consistent explanation for the ridge and desert boundary geometry.

C2weakest assumption

That a single representative tidal encounter parameter can be chosen to set the overall period offset across the sub-Neptune to super-Neptune regime while the slope is independently reproduced by the survival formalism.

C3one line summary

High-eccentricity tidal migration reproduces the Neptunian desert boundary slope and produces the ridge overdensity through density-dependent survival and clustering just beyond the disruption limit.
