Properties of the Reissner-Nordström Spacetimes with a Nonzero Cosmological Constant
Zdeněk Stuchlík, Stanislav Hledík
Properties of the Reissner-Nordström black-hole and naked-singularity spacetimes with a nonzero cosmological constant are represented by their geodetical structure and embedding di…
Equatorial photon motion in the Kerr-Newman spacetimes with a non-zero cosmological constant
Zdeněk Stuchlík, Stanislav Hledík
Discussion of the equatorial photon motion in Kerr-Newman black-hole and naked-singularity spacetimes with a non-zero cosmological constant is presented. Both repulsive and attract…
Photon capture cones and embedding diagrams of the Ernst spacetime
Zdeněk Stuchlík, Stanislav Hledík
The differences between the character of the Schwarzschild and Ernst spacetimes are illustrated by comparing the photon capture cones, and the embedding diagrams of the $t=\mathrm{…
Extreme gravitational lensing in vicinity of Schwarzschild-de Sitter black holes
P. Bakala, P. Cermak, S. Hledik +2
We have developed a realistic, fully general relativistic computer code to simulate optical projection in a strong, spherically symmetric gravitational field. The standard theoreti…
Dynamical stability of fluid spheres in spacetimes with a nonzero cosmological constant
Stanislav Hledik, Zdenek Stuchlik, Kristina Mrazova
The Sturm-Liouville eigenvalue equation for eigenmodes of the radial oscillations is determined for spherically symmetric perfect fluid configurations in spacetimes with a nonzero…
Trapping of neutrinos in extremely compact stars
Zdenek Stuchlik, Martin Urbanec, Gabriel Torok +2
Trapping of neutrinos in extremely compact stars containing trapped null geodesics is studied. We calculated the ratio of produced to trapped neutrinos in the simplest model of uni…
