For anisotropic quark stars in full general relativity, f-mode frequency scales linearly with the square root of average density, and normalized damping time follows a linear trend with compactness, with anisotropy shifting both relations.

abstract
We explore the correlation between the pre-merger tidal deformability and the post-merger remnant oscillations seen in numerical simulation of neutron star binaries, with the aim of understanding to what extent the physics support the existence of such a relation. We consider the impact of thermal and rotational effects and argue that the proposed relation does, indeed, make sense and provide simple arguments that help explain the result.

Quasi-normal f-modes of anisotropic quark stars in full general relativity
For anisotropic quark stars in full general relativity, f-mode frequency scales linearly with the square root of average density, and normalized damping time follows a linear trend with compactness, with anisotropy shifting both relations.
