Finite axisymmetric charged dust disks in conformastatic spacetimes
Guillermo A. Gonzalez, Antonio C. Gutierrez-Pineres, Paolo A. Ospina
An infinite family of axisymmetric charged dust disks of finite extension is presented. The disks are obtained by solving the vacuum Einstein-Maxwell equations for conformastatic s…
Chaotic Motion Around Stellar Objects with Octupolar Deformation: Newtonian and Post Newtonian Approaches
Javier Ramos-Caro, Framsol Lopez-Suspes, Guillermo A. Gonzalez
Regular and chaotic test particle motion in gravitational fields due to stellar bodies with quadrupolar and octupolar deformation are studied using Poincare surfaces of section. In…
Fokker-Planck-Rosenbluth-Type Equations for Self-gravitating Systems in 1PN Approximation
Javier Ramos-Caro, Guillermo A. Gonzalez
We present two formulations of Fokker-Planck-Rosenbluth-type (FPR) equations for many-particle self-gravitating systems, with first order relativistic corrections in the post-Newto…
Exact General Relativistic Thick Disks
Guillermo A. Gonzalez, Patricio S. Letelier
A method to construct exact general relativistic thick disks that is a simple generalization of the ``displace, cut and reflect'' method commonly used in Newtonian, as well as, in…
Rotating Relativistic Thin Disks as Sources of the Taub-NUT Solution
Guillermo A. Gonzalez
Rotating disks with nonzero radial pressure and finite radius are studied. The models are based in the Taub-NUT metric and constructed using the well-known ``displace, cut and refl…
