论文摘要
我们提供了一个分析势密度对的家庭，可以将其组合起来，以现实的方式描述银河条，包括方形/花生组件。我们使用两个合理的复合模型来说明这一点。可以免费提供用于评估潜力，力，密度和投影密度的计算机代码。
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 reasonable compound models. Computer code for the evaluation of potential, forces, density, and projected density is freely provided.
