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…
A Comment on Bonnor-Steadman Closed Timelike Curves
Valeria M. Rosa, Patricio S. Letelier
The existence and stability closed timelike curves in a Bonnor-Ward spacetime without torsion line singularities is shown by exhibiting particular examples.
Linear Stability of Closed Timelike Geodesics
Valéria M. Rosa, Patricio S. Letelier
The linear stability of closed timelike geodesics (CTGs) is analyzed in two spacetimes with cylindrical sources, an infinite rotating dust cylinder, and a cylindrical cloud of stat…
Spinning Strings, Black Holes and Stable Closed Timelike Geodesics
Valeria M. Rosa, Patricio S. letelier
The existence and stability under linear perturbation of closed timelike curves in the spacetime associated to Schwarzschild black hole pierced by a spinning string are studied. Du…
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…
