Gravitational asteroseismology studies applied to neutron stars aim to relate stellar properties to characteristics of the gravitational wave signal. In the case of non-rotating neutron stars, gravitational waves produced by linear oscillations are characterized by their pulsation frequency and damping timescale. We focus on the main emitter, the quadrupole fundamental mode, and review a higher order empirical relation for the damping timescale, which was initially presented in [1]. The relation is accurate throughout a wide range of compactness, covering the expected values for neutron stars, while involving only the mass and radius and no other quantity, such as the moment of inertia.
