Quasi-universal relations connect the trace anomaly profile of neutron star matter to stellar compactness, moment of inertia, and tidal deformability, yielding a central value estimate of Δ_c = 0.1770^{+0.0365}_{-0.0432} for a 1.4 M_⊙ star.

Two inference frameworks are developed for neutron star properties from r-mode gravitational waves, one assuming electromagnetic distance and the other estimating distance via universal relations plus an assumed equation of state, with Fisher-matrix error estimates.
