The generalized Lemaitre-Tolman-Bondi solutions with nonzero pressure in modeling the cosmological black holes
E. Kopteva, P. Jaluvkova, Z. Stuchlik
In this work we have obtained the set of new exact solutions of the Einstein equations that generalize the known Lemaitre-Tolman-Bondi solution for the certain case of nonzero pres…
General relativistic polytropes with a repulsive cosmological constant
Zdeněk Stuchlík, Stanislav Hledík, Jan Novotný
Spherically symmetric equilibrium configurations of perfect fluid obeying a polytropic equation of state are studied in spacetimes with a repulsive cosmological constant. The confi…
Efficiency of the Keplerian accretion in the Braneworld Kerr--Newman Spacetimes and mining instability of some naked singularity spacetimes
Martin Blaschke, Zdeněk Stuchlík
We show that the~braneworld rotating Kerr--Newman black hole and naked singularity spacetimes with both positive and negative braneworld tidal charge parameter can be separated int…
The model of the black hole enclosed in dust. The flat space case
Pavlina Jaluvkova, Elena Kopteva, Zdenek Stuchlik
In this work the model is constructed to describe the black hole enclosed in the dust cosmological background in case of zero spatial curvature. This model is based on our exact so…
