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…
Potential-density pairs for bent bars
D. Vogt, P. S. Letelier
A method is presented to bend a thin massive line when the curvature is small. The procedure is applied to a homogeneous thin bar with two types of curvatures. One of them mimics a…
Analytical potential-density pairs for bars
D. Vogt, P. S. Letelier
An identity that relates multipolar solutions of the Einstein equations to Newtonian potentials of bars with linear densities proportional to Legendre polynomials is used to constr…
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…
Analytical potential-density pairs from complex-shifted Kuzmin-Toomre discs
D. Vogt, P. S. Letelier
The complex-shift method is applied to the Kuzmin-Toomre family of discs to generate a family of non-axisymmetric flat distributions of matter. These are then superposed to constru…
