| The minimum-maximum behavior of orbital velocity of a rotating test body around a Kerr black hole is known as the Aschenbach effect. In this paper, we generalize this idea for the charged Kerr black hole(Kerr-Newman) in the de Sitter spacetime to find an indirect measurement of the charge of a black hole or rotating objects same as the other hair of the black hole. |
