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…
Gravitational excitation of high frequency QPOs
Zdeněk Stuchlík, Sushan Konar, John C. Miller +1
We discuss the possibility that high-frequency QPOs in neutron-star binary systems may result from forced resonant oscillations of matter in the innermost parts of the accretion di…
Optical reference geometry of the Kerr-Newman spacetimes
Zdeněk Stuchlík, Stanislav Hledík, Josef Juráň
Properties of the optical reference geometry related to Kerr-Newman black-hole and naked-singularity spacetimes are illustrated using embedding diagrams of their equatorial plane.…
