A family of potential-density pairs for galactic bars
Abstract: We present a family of analytical potential-density pairs for barred discs, which can be combined to describe galactic bars in a realistic way, including boxy/peanut components. We illustrate this with two reasonably realistic compound models. Computer code for the evaluation of potential,...

| Summary: | Abstract: We present a family of analytical potential-density pairs for barred discs, which can be combined to describe galactic bars in a realistic way, including boxy/peanut components. We illustrate this with two reasonably realistic compound models. Computer code for the evaluation of potential, forces, density, and projected density is freely provided. |
