Strong gravitational lensing by a Reissner-Nordström naked singularity with a marginally unstable photon sphere
Tadashi Sasaki
We investigate strong gravitational lensing by a marginally unstable photon sphere in a Reissner-Nordström naked singularity spacetime. Using the Picard-Fuchs equation, we derive f…

Deflection of Light by a Reissner-Nordström Black Hole and Painlevé VI equation
Tadashi Sasaki
We consider the bending angle of the trajectory of a photon incident from and deflected to infinity around a Reissner-Nordström black hole. We treat the bending angle as a function…
