This black hole differs from a Schwarzschild-Kerr black hole by the dimensionless parameter $\\beta$. The size of the shadow depends on this parameter. Increasing the value of the parameter $\\beta$ shrinks the shadow. A critical value of the parameter $\\beta$ is found to be $\\beta_{\\rm crit}=0.40263$. The shadow for the horizonless dark compact object has been analysed for the static, spherically symmetric case and compared with M87* and Sgr A* data.
