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.
