Query: Inner-most stable circular orbit in Kerr-MOG black hole   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.
