Periodic orbits and observational accretion disk around a Schwarzschild-like black hole surrounded by dark matter halo
Javokhir Sharipov, Tursunali Xamidov, Qiang Wu +2
In this work, we investigate the dynamics of periodic orbits and the properties of accretion disks around a Schwarzschild-like black hole (BH) immersed in a King-type dark matter (…

Spherical Accretion Flow onto General Parameterized Spherically Symmetric Black Hole Spacetimes
Sen Yang, Cheng Liu, Tao Zhu +4
The transonic phenomenon of black hole accretion and the existence of the photon sphere are the characteristics of strong gravitational fields near a black hole horizon. In this wo…

Thin Accretion Disk around a four-dimensional Einstein-Gauss-Bonnet Black Hole
Cheng Liu, Tao Zhu, Qiang Wu
Recently a novel four-dimensional Einstein-Gauss-Bonnet (4EGB) theory of gravity was proposed by Glavan and Lin [D. Glavan and C. Lin, Phys. Rev. Lett. 124, 081301 (2020)] which in…
