Can Asteroseismic Structure Inversions Be Performed in Structure-Dependent Coordinates?

Radial modes of pressure bumps and dips in astrophysical discs
Pressure extrema in discs function as waveguides for topological modes, with the fundamental bump mode able to propagate at all frequencies and the gap mode fixed to one frequency with arbitrary vertical phase velocity.
