Resolving an Asteroseismic Catastrophe: Structural Diagnostics from p-mode Phase Functions off the Main Sequence

J. M. Joel Ong, Christopher J. Lindsay, Claudia Reyes +2

On the main sequence, the asteroseismic small frequency separation $\hat{I}´\hat{I}{½}_{02}$ between radial and quadrupole p-modes is customarily interpreted to be a direct diagnostic of interna…
