GW strain evolution with frequency for the FXTs analyzed in this work. Each shaded region represents the GW strain considering eight EoS (see Table 3) at different distances. The cyan, gray, and black lines are the sensitivity limits for aLIGO, ET, and CE GW telescopes, respectively. For the FXTs without redshifts (FXTs 7, 10, 12, 15, and 20), we assumed z = 0.5 and 1.0 (see Table 2).
