Circular Orbits in Einstein-Gauss-Bonnet Gravity
Valeria M. Rosa, Patricio S. Letelier
The stability under radial and vertical perturbations of circular orbits associated to particles orbiting a spherically symmetric center of attraction is study in the context of th…

Stability of Closed Timelike Geodesics
V. M. Rosa, P. S. Letelier
The existence and stability under linear perturbations of closed timelike geodesics (CTGs) in Bonnor-Ward spacetime is studied in some detail. Regions where the CTG exist and are l…

Stability of Closed Timelike Curves in Goedel Universe
Valeria M. Rosa, Patricio S. Letelier
We study, in some detail, the linear stability of closed timelike curves in the Goedel metric. We show that these curves are stable. We present a simple extension (deformation) of…
