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…
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…
Analytical Potential-Density Pairs for Flat Rings and Toroidal Structures
D. Vogt, P. S. Letelier
The Kuzmin-Toomre family of discs is used to construct potential-density pairs that represent flat ring structures in terms of elementary functions. Systems composed of two concent…
