Fractional Derivative Approach to the Self-gravitation Equation
Juan F. Pedraza, Javier Ramos-Caro, Guillermo A. Gonzalez
A new formalism is presented for finding equilibrium distribution functions for axisymmetric systems. The formalism, obtainded by using the concept of fractional derivatives, gener…
An Infinite Family of Self-consistent Models for Axisymmetric Flat Galaxies
Juan F. Pedraza, Javier Ramos-Caro, Guillermo A. Gonzalez
We present the formulation of a new infinite family of self-consistent stellar models, designed to describe axisymmetric flat galaxies. The corresponding density-potential pair is…
Chaotic and regular motion around generalized Kalnajs discs
Javier Ramos-Caro, Framsol Lopez-Suspes, Guillermo A. Gonzalez
The motion of test particles in the gravitational fields generated by the first four members of the infinite family of generalized Kalnajs discs, is studied. In first instance, we…
Distribution functions for a family of axially symmetric galaxy models
Guillermo A. González, Juan F. Pedraza, Javier Ramos-Caro
We present the derivation of distribution functions for the first four members of a family of disks, previously obtained in (MNRAS, 371, 1873, 2006), which represent a family of ax…
