We develop a phenomenological, physically motivated, model for the effective tidal deformability of a neutron star binary, adding the frequency dependence (associated with the star’s fundamental mode of oscillation) that comes into play during the late stages of an inspiral. Testing the model against alternative descriptions, we find that it provides an accurate representation of the tidal deformability. The simplicity of the model makes it an attractive alternative for a gravitational-wave data analysis implementation as it facilitates an inexpensive construction of a large number of templates covering the relevant parameter space.
