Null geodesics in the C-metric with cosmological constant
Yen-Kheng Lim
In this paper we study the motion of photons or massless particles in the C-metric with cosmological constant. The Hamilton--Jacobi equations are known to be completely separable,…

Hypocycloid motion in the Melvin magnetic universe
Yen-Kheng Lim
The trajectory of a charged test particle in the Melvin magnetic universe is shown to take the form of hypocycloids in two different regimes, first of which is the class of perturb…

Orbital mechanics and quasiperiodic oscillation resonances of black holes in Einstein-Æther theory
Mustapha Azreg-Aïnou, Zihang Chen, Bojun Deng +4
In this paper, we study the motion of test particles around two exact charged black-hole solutions in Einstein-Æther theory. Specifically, we first consider the quasi-periodic osci…
