We show that these black holes have arbitrarily short hair, and argue for stability by showing that they can arise from dynamical collapse. We also show that a recent `no short hair' theorem does not apply to these solutions.doi:10.1142/S0218271897000340David Brown, J....
We show that in all theories in which black hole hair has been discovered, the region with non-trivial structure of the non-linear matter fields must extend beyond $3/ 2$ the horizon radius, independently of all other parameters present in the theory. We argue that this is a universal ...
In our paper on hairy Kerr black holes, we primarily discuss the impact of the hair parameters (α,l0) on its event horizon. This is because we know that the event horizon of the hairy Kerr black hole is strongly dependent on the hair parameters (α,l0). The event horizon of the ha...

we conduct a thorough investigation into how the three parameters of the model influence the onset and intensity of the instability. Our analysis offers further insights into the possible emergence of this instability in spherical regular black holes and its association with the nonlinear effects of ...

Black holes may sport a luxurious head of "hair" made up of ghostly, zero-energy particles, says a new hypothesis proposed by Stephen Hawking and other physicists. The new paper, which was published online Jan. 5 in the preprint journal arXiv, proposes that at least some of the information...
Such interaction terms can modify the behavior of electromagnetic field propagation, especially in regions with a strong scalar field background, such as near black holes or on cosmological scales. Additionally, the introduction of a scalar field can also be seen as a modification of the standard ...
However, intu- itively, the condition for the existence of hairy black holes is that the self-interaction of the scalar field together with the gravitational interaction should combine such that the near- horizon hair does not collapse into the black hole while the far-region hair does not ...
