Nondivergent deflection of light around a photon sphere of a compact object
We demonstrate that the location of a stable photon sphere (PS) in a compact object is not always an edge such as the inner boundary of a black hole shadow, whereas the location of an unstable PS is known to be the shadow edge; notably, in the Schwarzschild black hole. If a static spherically symmet...
