Defrosting the Born-Infeld dyonic frozen star with tachyon matter: spectrum of oscillations
Ram Brustein, A. J. M. Medved, Tamar Simhon
The frozen star is a model for the interior of an astrophysical black hole that is externally indistinguishable from the singular geometry of a Schwarzschild black hole, even thoug…
Formation of Frozen Stars from collapsing matter by tunneling
Ram Brustein, A. J. M. Medved, Tamar Simhon
The frozen star is a type of black hole mimicker: An ultracompact object whose exterior geometry resembles that of a general-relativistic black hole but differs in its matter compo…
Defrosting frozen stars: spectrum of non-radial oscillations
Ram Brustein, A. J. M. Medved, Tom Shindelman
The frozen star model describes a type of black hole mimicker; that is, a regular, horizonless, ultracompact object that behaves just like a Schwarzschild black hole from an extern…
Kerr Black hole mimickers sourced by a string fluid
Ram Brustein, A. J. M. Medved, Tamar Simhon
We present rotating solutions of Einstein's gravity coupled to an effective Born-Infeld theory that describes the end of open-string tachyon condensation after the decay of an unst…
Frozen stars: Black hole mimickers sourced by a string fluid
Ram Brustein, A. J. M. Medved
The frozen star is a non-singular, ultracompact object that, to an external observer, looks exactly like a Schwarzschild black hole, but with a different interior geometry and matt…
Sourcing the Kerr geometry
Ram Brustein, A. J. M. Medved
The Kerr metric is a vacuum solution of the Einstein equations outside of a rotating black hole, but what interior matter is actually rotating and sourcing the Kerr geometry? Here,…
