Null geodesics in five-dimensional Reissner-Nordström anti-de Sitter black hole

Abstract

The study of the motion of photons around massive bodies is one of the most useful tools to know the geodesic structure associated with said gravitational source. In the present work, different possible paths projected in an invariant hyperplane are investigated, considering five-dimensional Reissner-Nordström anti-de Sitter black hole. Also, we study some observational test such as the bending of light and the Shapiro time delay effect. Mainly, we found that the motion of photons follows the hippopede of Proclus geodesic, which is a new type of trajectory of second kind, being the Limaçon of Pascal their analogue geodesic in four-dimensional Reissner-Nordström anti-de Sitter black hole.
