Trapped photon region in the phase space of sub-extremal Kerr-Newman and Kerr-Sen spacetimes
Carla Cederbaum, Karim Mosani
We analyse the geometry and topology of the trapped photon region in the domain of outer communication of sub-extremal Kerr-Newman and Kerr-Sen spacetimes. Specifically, we show th…
