Figure 27

Figure 27: Schematic figure for the gravitational-wave spectrum for the same masses of BH and NS with different EOS of NS for a = 0. For (i)-a, tidal disruption occurs far outside the ISCO. For (i)-b, tidal disruption occurs near the ISCO. For (ii), tidal disruption does not occur and the NS is simply swallowed by the BH. We refer to the spectra (i)-a and (i)-b as type-I and the spectrum (ii) as type-II. For a = 0 and 0.13 ≲ 𝒞 ≲ 0.2, the type-I spectrum is seen only for small values of the mass ratio with Q ≲ 3. The filled and open circles denote the cutoff frequencies associated with tidal disruption and QNM, respectively.
