Structure-preserving numerical simulations of test particle dynamics around slowly rotating neutron stars within Hartle-Thorne approach
Misbah Shahzadi, Martin Kolos, Rabia Saleem +2
In this paper, we explore the chaotic signatures of the geodesic dynamics for particles moving in the slowly rotating Hartle-Thorne spacetime; an approximate solution of vacuum Ein…
String loop vibration around Schwarzschild black hole
Mariia Churilova, Martin Kološ, Zdeněk Stuchlík
String loop vibrations in a central plane of a Schwarzschild black hole are investigated for various string equations of state. We discuss string loop stability and derive frequenc…
Testing alternative spacetimes by high-frequency quasi-periodic oscillations observed in microquasars and active galactic nuclei
Misbah Shahzadi, Martin Kološ, Rabia Saleem +1
In this article, we try to capture the influence of deviation from standard Kerr black hole spacetime on observed high-frequency quasi-periodic oscillations signal. We explore the…
Charged particle dynamics in parabolic magnetosphere around Schwarzschild black hole
Martin Kološ, Misbah Shahzadi, Arman Tursunov
The study of charged particle dynamics in the combined gravitational and magnetic field can provide important theoretical insight into astrophysical processes around black holes. I…
