Abstract: The following theorem is established. Among all static, asymptotically flat vacuum space-times with closed simply connected equipotential surfaces ${g}_{00}=\mathrm{constant}$, the Schwarzschild solution is the only one which has a nonsingular infinite-red-shift surface ${g}_{00}=0$. Thus there exists no static asymmetric perturbation of the Schwarzschild manifold due to internal sources (e.g., a quadrupole moment) which will preserve a regular event horizon. Possible implications of this result for asymmetric gravitational collapse are briefly discussed.

Hairy black holes in a box
TL;DR: In this article, a systematic study of the phases of gravity coupled to an electromagnetic field and a charged scalar in flat space, with box boundary conditions, is presented, and it is shown that the system admits both boson stars as well as hairy black holes as solutions, providing another way to evade flat space no-hair theorems.

Black hole hair formation in shift-symmetric generalised scalar-tensor gravity
TL;DR: In this article, the authors explore the dynamical formation of scalar hair and show that the scalar relaxes at late times to the known, static, analytic configuration associated with a hairy, spherically symmetric black hole.
Black holes in vector-tensor theories
TL;DR: In this paper, the authors studied static and spherically symmetric black hole (BH) solutions in second-order generalized Proca theories with nonminimal vector field derivative couplings to the Ricci scalar, the Einstein tensor, and the double dual Riemann tensor.

Parametric nonholonomic frame transforms and exact solutions in gravity
TL;DR: In this paper, a generalized geometric method is developed for constructing exact solutions of gravitational field equations in Einstein theory and generalizations, and five classes of exact off-diagonal solutions are constructed in vacuum Einstein and in string gravity describing solitonic pp-wave interactions.

Stability of a Schwarzschild Singularity
TL;DR: In this article, it was shown that a Schwarzschild singularity, spherically symmetrical and endowed with mass, will undergo small vibrations about the spherical form and therefore remain stable if subjected to a small nonspherical perturbation.

Maximal analytic extension of the Kerr metric
TL;DR: Kruskal's transformation of the Schwarzschild metric is generalized to apply to the stationary, axially symmetric vacuum solution of Kerr, and is used to construct a maximal analytic extension of the latter.

Collinear particles and bondi dipoles in general relativity
W. Israel,K. A. Khan +1 more
TL;DR: In this article, a static vacuum line element is derived which represents the field of a collinear set of spherically symmetric masses and a limiting process applied to this line-element yields an explicit global solution of a problem first considered by Bondi.

Possible Instability in the Self-closure Phenomenon in Gravitational Collapse
TL;DR: In this paper, the authors point out that models with exact spherical symmetry possess idiosyncrasies which render them dangerous, and perhaps misleading, as a basis for induction, and they suggest that such models are not suitable for induction.
