Equatorial photon motion in the Kerr-Newman spacetimes with a non-zero cosmological constant
Zdeněk Stuchlík, Stanislav Hledík
Discussion of the equatorial photon motion in Kerr-Newman black-hole and naked-singularity spacetimes with a non-zero cosmological constant is presented. Both repulsive and attract…

Optical reference geometry of the Kerr-Newman spacetimes
Zdeněk Stuchlík, Stanislav Hledík, Josef Juráň
Properties of the optical reference geometry related to Kerr-Newman black-hole and naked-singularity spacetimes are illustrated using embedding diagrams of their equatorial plane.…
