复数位移Kuzmin-Toomre圆盘的解析势-密度对

Analytical potential-density pairs from complex-shifted Kuzmin-Toomre discs

D. Vogt, P. S. Letelier

摘要:

复位移法应用于Kuzmin Toomre族的磁盘产生一个家庭的非轴对称平坦的物质分布。然后将它们叠加以构造非轴对称的扁平环。我们还考虑了通过适当的变换从这些非轴对称平板系统中得到的三轴势-密度对。还讨论了复数位移势-密度对虚部的使用。

英文摘要:

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 construct non-axisymmetric flat rings. We also consider triaxial potential-density pairs obtained from these non-axisymmetric flat systems by means of suitable transformations. The use of the imaginary part of complex-shifted potential-density pairs is also discussed.
