Upper bounds on the compactness at the innermost light ring of anisotropic horizonless spheres
Abstract In the background of isotropic horizonless spheres, Hod recently provided an analytical proof of a bound on the compactness at the innermost light ring with the dominant energy condition. In this work, we extend the discussion of isotropic spheres to anisotropic spheres. With the dominant e...
