Role of electric charge in shaping equilibrium configurations of fluid tori encircling black holes
Jiří Kovář, Petr Slaný, Zdeněk Stuchlík +3
Astrophysical fluids may acquire non-zero electrical charge because of strong irradiation or charge separation in a magnetic field. In this case, electromagnetic and gravitational…
Neutrino trapping in braneworld extremely compact stars
Zdenek Stuchlik, Jan Hladik, Martin Urbanec
Extremely Compact Stars (ECS) contain trapped null geodesics. When such objects enter the evolution period admitting geodetical motion of neutrinos, certain part of neutrinos produ…
Photon and neutrino redshift in the field of braneworld compact stars
Jan Hladik, Zdenek Stuchlik
We study gravitational redshift of photons and neutrinos radiated by the braneworld neutron or quark stars that are considered in the framework of the simple model of the internal…
Non-monotonic Keplerian velocity profiles around near-extreme braneworld Kerr black holes
Zdenek Stuchlik, Martin Blaschke, Petr Slany
We study the non-monotonic Keplerian velocity profiles related to locally non-rotating frames (LNRF) in the field of near-extreme braneworld Kerr black holes and naked singularitie…
Confronting the models of 3:2 quasiperiodic oscillations with the rapid spin of the microquasar GRS 1915+105
Gabriel Torok, Andrea Kotrlova, Eva Sramkova +1
Spectral fitting of the spin a in the microquasar GRS 1915+105 estimate values higher than a=0.98. However, there are certain doubts about this (nearly) extremal number. Confirming…
Appearance of Keplerian discs orbiting Kerr superspinars
Zdenek Stuchlik, Jan Schee
We study optical phenomena related to appearance of Keplerian accretion discs orbiting Kerr superspinars predicted by the string theory. The superspinar exterior is described by th…
