Relativistic ring models
M. Ujevic, P. S. Letelier, D. Vogt
Relativistic thick ring models are constructed using previously found analytical Newtonian potential-density pairs for flat rings and toroidal structures obtained from Kuzmin-Toomr…
Newtonian and General Relativistic Models of Spherical Shells - II
D. Vogt, P. S. Letelier
A family of potential-density pairs that represent spherical shells with finite thickness is obtained from the superposition of spheres with finite radii. Other families of shells…
Newtonian and General Relativistic Models of Spherical Shells
D. Vogt, P. S. Letelier
A family of spherical shells with varying thickness is derived by using a simple Newtonian potential-density pair. Then, a particular isotropic form of a metric in spherical coordi…
New Models of General Relativistic Static Thick Disks
D. Vogt, P. S. Letelier
New families of exact general relativistic thick disks are constructed using the ``displace, cut, fill and reflect'' method. A class of functions used to ``fill'' the disks is deri…
A General Relativistic Model for the Gravitational Field of Active Galactic Nuclei Surrounded by a Disk
D. Vogt, P. S. Letelier
An exact but simple general relativistic model for the gravitational field of active galactic nuclei is constructed, based on the superposition in Weyl coordinates of a black hole,…
Exact Relativistic Static Charged Perfect Fluid Disks
D. Vogt, P. S. Letelier
Using the well-known ``displace, cut and reflect'' method used to generate disks from given solutions of Einstein field equations, we construct static charged disks made of perfect…
