Synthetic Fe Kα line profiles from a geometrically thin disk with q = 0 (i.e., constant emissivity per unit area) in a Kerr-like wormhole with the deformation parameter λ = 0.9. The different colors represent different spins, a_* = 0 (dash-dotted orange), 0.3 (dashed red), 0.6 (solid green), and 0.998 (dotted purple). The dash-dotted blue line represents the case of a Kerr black hole (λ = 0) with a_* = 0.998. Other model parameters are the same as those in Fig. 3.
