Neutral particle motion around a Schwarzschild-de Sitter Black Hole in f(R) gravity

This article investigates the presence of a static spherically symmetric solution in the metric f(R) gravity. Consequently, we have examined the presence of horizons for the extreme and hyperextreme Schwarzschild-de Sitter solution. Further, we have investigated the orbital motion of a time-like particle around the Schwarzschild-dS solution by forming the constraints for the existence of circular orbits and have subsequently developed an approximation to the innermost stable circular orbit (ISCO).

Orbital Motion of a test particle around a Schwarzschild's Black Hole in STVG gravity

In this article, we have examined the existence of a static spherically symmetric solution in the Scalar Tensor Vector Gravity (STVG) and investigated its horizon distances to develop boundary limitations for our test particle. We have computed the Kretschmann invariant of the metric to study the singularities and verify that it reduces to general relativity's Kretschmann invariant as $\alpha\rightarrow0$. Further, we investigated the orbital motion of a time-like and light-like test particle around the static solution by developing an effective potential and the radius of the innermost stable circular orbit (ISCO).
