# Inner-most stable circular orbit in Kerr-MOG black hole

## TL;DR

This paper investigates the properties of the innermost stable circular orbit (ISCO) around Kerr-MOG black holes, highlighting differences from standard Kerr black holes due to a repulsive parameter in modified gravity.

## Contribution

It introduces the ISCO analysis for Kerr-MOG black holes, a solution incorporating a Yukawa-like repulsive parameter, extending understanding of strong gravity regimes.

## Key findings

- ISCO characteristics differ from Kerr black holes due to the repulsive parameter
- The modified gravity affects the stability and radius of circular orbits
- Insights into quantum gravity effects on black hole orbits

## Abstract

We study the inner-most stable circular orbit(ISCO) of Kerr black hole in MOdified gravity(Kerr-MOG black hole) which is one of the exact solution of the field equation of modified gravity in strong gravity regime. Kerr-MOG black hole is constructed commonly known kerr metric in Boyer-Lindquist coordinate by adding repulsive parameter like Yukawa force which explained in quantum gravity. We explore what is some differences of the ISCOs of Kerr-MOG black hole and kerr black hole.
