The existence of null circular geodesics outside extremal spherically symmetric asymptotically flat hairy black holes
Abstract The existence of null circular geodesics in the background of non-extremal spherically symmetric asymptotically flat black holes has been proved in previous works. An interesting question that remains, however, is whether extremal black holes possess null circular geodesics outside horizons...
