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

摘要： 研究光子在大质量天体周围的运动是了解与该引力源相关的测地线结构的最有力工具之一。 在本工作中，我们研究了投影在一个不变超平面内的不同可能路径，考虑的是五维Reissner-Nordström反德西特黑洞。 此外，我们还研究了一些观测检验，如光的偏折和Shapiro时间延迟效应。 主要发现是，光子的运动遵循Proclus测地线的hippopede轨迹，这是一种新的第二类轨迹，而Limaçon轨迹则是四维Reissner-Nordström反德西特黑洞中的类比测地线。 显示英文摘要

摘要： 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-Nordstr\"om 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 Lima\c{c}on of Pascal their analogue geodesic in four-dimensional Reissner-Nordstr\"om anti-de Sitter black hole.
