We investigate the astrophysical aspects of the rotating Fisher–Janis–Newman–Winicour (FJNW) metric recently derived in [1]. The Hamilton–Jacobi equation is used to obtain the shadow of the rotating FJNW metric. We find that increasing the angular momentum parameter a and the metric parameter γ leads to an increase in the size of the shadow. Finally, we study the deflection angle of light in the rotating FJNW spacetime.
