During the 1990s a large amount of work was dedicated to studying general relativity coupled to non-Abelian Yang-Mills type theories. Several remarkable results were accomplished. In particular, it was shown that the magnetic monopole, a solution of the Yang-Mills-Higgs equations can indeed be coupled to gravitation. For a low Higgs mass it was found that there are regular monopole solutions, and that for a sufficiently massive monopole the system develops an extremal magnetic Reissner… Expand
Thick shells and stars in Majumdar-Papapetrou general relativity
The Majumdar-Papapetrou system is the subset of the Einstein-Maxwell-charged dust matter theory, when the charge of each particle is equal to its mass. Solutions for this system are less difficult toExpand
Bonnor stars in d spacetime dimensions
Bonnor stars are regular static compact configurations in equilibrium, composed of an extremal dust fluid, i.e., a charged dust fluid where the mass density is equal to the charge density inExpand
Mass formula for quasi-black holes
A quasi-black hole, either nonextremal or extremal, can be broadly defined as the limiting configuration of a body when its boundary approaches the body's quasihorizon. We consider the massExpand
Collapsing and static thin massive charged dust shells in a Reissner-Nordstrom black hole background in higher dimensions
The problem of a spherically symmetric charged thin shell of dust collapsing gravitationally into a charged Reissner–Nordstrom black hole in d space–time dimensions is studied within the theory ofExpand
Charged cosmological dust solutions of the coupled Einstein and Maxwell equations
It is well known through the work of Majumdar, Papapetrou, Hartle, and Hawking that the coupled Einstein and Maxwell equations admit a static multiple blackhole solution representing a balancedExpand
Thermodynamics of black holes from equipartition of energy and holography
A gravitational potential in the relativistic case is introduced as an alternative to Wald's potential used by Verlinde, which reproduces the familiar entropy/area relation S = A/4 (in the naturalExpand
Gravastars supported by nonlinear electrodynamics
Gravastar models have recently been proposed as an alternative to black holes, mainly to avoid the problematic issues associated with event horizons and singularities. In this work, a wide variety ofExpand
Truly naked black holes and quasi-black holes
Usually, a black hole horizon hides singularities beyond it, being itself perfectly regular. We discuss somewhat unusual cases when the system can combine regular and singular features due to theExpand
Entropy of quasiblack holes
We trace the origin of the black hole entropy S, replacing a black hole by a quasiblack hole. Let the boundary of a static body approach its own gravitational radius, in such a way that aExpand
Manifestation of singular features in black hole horizons and quasi-horizons
Usually, a black hole horizon hides singularities beyond it, being by itself perfectly regular. I discuss somewhat unusual cases when a system can combine regular and singular features due to theExpand

It is shown that nonsingular monopole solutions exist only if the Higgs field vacuum expectation value v is less than or equal to a critical value v sub cr, which is of the order of the Planck mass. Expand

TLDR
A careful analysis of solutions near the transition to a black hole shows that the monopole loses its non-Abelian hair as it develops a horizon. Expand

TLDR
It is shown that finite energy magnetic monopole solutions also exist within a class of purely Abelian gauge theories containing charged vector mesons, even though the possibility of nontrivial topology does not even arise provided that certain relationships among the parameters of the theory are satisfied.

Eluding the no-hair conjecture: Black holes in spontaneously broken gauge theories.
TLDR
It is shown that the standard black hole no-hair theorem underlying this belief, although true in the Abelian setting, does not necessarily extend to the non-Abelian case, indicating the possibility of solutions with nontrivial gauge and Higgs configurations decaying exponentially outside of the horizon.
