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…
Multipolar corrections for Lense-Thirring precession
Marcelo Zimbres, Patricio S. Letelier
For stationary axially symmetric spacetimes we find a simple expression for the Lense-Thirring precession in terms of the Ernst potential. This expression is used to compute, in th…
Static charged fluid around a massive magnetic dipole
Jose D. Polanco, Patricio S. Letelier, Maximiliano Ujevic
An analytical solution of Einstein-Maxwell equations with a static fluid as a source is presented. The spacetime is represented by the axially symmetric Weyl metric and the energy-…
Quantum Singularities in Spacetimes with Spherical and Cylindrical Topological Defects
Paulo M. Pitelli, Patricio S. Letelier
Exact solutions of Einstein equations with null Riemman-Christoffel curvature tensor everywhere, except on a hypersurface, are studied using quantum particles obeying the Klein-Gor…
Riemann-Christoffel flows
Patricio S. Letelier
A geometric flow based in the Riemann-Christoffel curvature tensor that in two dimensions has some common features with the usual Ricci flow is presented. For dimensional space…
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…
