Synthetic Fe Kα line profiles from a geometrically thin disk in a Kerr black hole (dashed blue lines) and Kerr-like wormhole with the deformation parameter λ = 0.9 (solid lines). Different colors represent different spins, a* = 0.3 (red), 0.6 (green), and 0.998 (purple). All curves are normalized and plotted as E2 dN/dE. Other model parameters are the same as in Fig. 2.
