TY - JOUR ID - 58081 AU - Pugliese, Daniela - Quevedo, Hernando PY - 2021 TI - Repulsive gravity effects in horizon formation: Horizon remnants in naked singularities JF - General Relativity and Gravitation VL - 53 IS - 10 SP - "89-1"-"89-14" EP - "89-1"-"89-14" SN - 00017701 KW - Black holes;Naked singularities;Killing horizons;Light surfaces;Photon orbits UR - https://link.springer.com/article/10.1007/s10714-021-02858-4 N2 - Repulsive gravity is a well known characteristic of naked singularities. In this work, we explore light surfaces and find new effects of repulsive gravity. We compare Kerr naked singularities with the corresponding black hole counterparts and find certain structures that are identified as horizon remnants. We argue that these features might be significant for the comprehension of processes that lead to the formation or eventually destruction of black hole Killing horizons. These features can be detected by observing photon orbits, particularly close to the rotation axis, which can be used to distinguish naked singularities from black holes. ER -
