Precision tests of analytical tail-term approximations for radiation reaction in Schwarzschild spacetime
Bakhtinur Juraev, Arman Tursunov, Zdeněk Stuchlík +2
We investigate the consistency and precision of approximate analytical expressions for the electromagnetic self-force acting on a charged particle in Schwarzschild spacetime endowe…
Electromagnetic radiation-reaction near black holes: orbital widening and the role of the tail
Bakhtinur Juraev, Arman Tursunov, Zdeněk Stuchlík +2
We investigate the orbital evolution of a classical charged particle around a Schwarzschild black hole immersed in an external, uniform magnetic field, taking into full account bot…
Stability of the rotating string loops in Kerr spacetime
Mariia Churilova, Zdeněk Stuchlík
We study stability of the circular string loops rotating in the equatorial plane of Kerr spacetime against equatorial and polar perturbations. We consider motion of such string loo…
Dark matter halos modeled by polytropic spheres influenced by the relict cosmological constant and trapping polytropes forming supermassive black holes
Zdeněk Stuchlík, Jan Novotný, Jan Hladík
We study dark matter halos modeled by general relativistic polytropic spheres in spacetimes with the repulsive cosmological constant representing vacuum energy density, governed by…
Exploring a Novel Feature of Ellis Spacetime: Insights into Scalar Field Dynamics
Bobur Turimov, Akbar Davlataliev, Bobomurat Ahmedov +1
We have studied neutral and charged massive particles dynamics in Ellis spacetime in the presence of the external scalar field. Focusing on the circular motion of massive particles…
Can electromagnetic charge inhabit in Rastall gravity?
Bobir Toshmatov, Zdeněk Stuchlík, Bobomurat Ahmedov
One of the eminent generalizations of theory of general relativity is the Rastall gravity which was {constructed} based on the assumption of the non-conserved energy-momentum tenso…
