Effects of matter with anisotropic pressure on the Fan-Wang regular black hole shadows
Yergali Kurmanov, Orlando Luongo, Daulet Berkimbayev +4
We here investigate the consequences of an exotic fluid, exhibiting negative radial and tangential pressures, \emph{de facto} violating the Zel'dovich limit, on a regular solution…
Numerical analysis of quasiperiodic oscillations in the Hartle-Thorne spacetime
K. Boshkayev, T. Konysbayev, Ye. Kurmanov +2
We numerically analyze quasiperiodic oscillations (QPOs) using a well-established spacetime model with neutron star sources. Within the framework of general relativity, we present…
Geometric properties versus particle motion in the Fan-Wang spacetime
Gulnara Suliyeva, Kuantay Boshkayev, Talgar Konysbayev +7
In this work, we explore general relativistic effects and geometric properties of the Fan-Wang spacetime, one of the simplest regular solutions that can be obtained in nonlinear el…
Accretion disks properties around regular black hole solutions obtained from non-linear electrodynamics
Yergali Kurmanov, Kuantay Boshkayev, Talgar Konysbayev +5
We investigate a family of spherically symmetric, static, charged regular black hole solutions derived within the framework of Einstein-nonlinear electrodynamics. Our study focuses…
Luminosity of accretion disks around rotating regular black holes
Kuantay Boshkayev, Talgar Konysbayev, Yergali Kurmanov +4
We consider thin accretion disks in the field of a class of rotating regular black holes. For this purpose, we obtain the radius of the innermost stable circular orbit, …
