轴对称与三轴形MOND密度-势能对

我们提出一种基于对球对称势能变形的简单方法，以构建显式的轴对称与三轴形MOND密度-势能对。presented general guidelines for suitable deformations, ensuring the resulting density distribution is nowhere negative. This flexible method offers for the first time the possibility to study the MOND gravitational field for sufficiently general and realistic density distributions without resorting to sophisticated numerical codes. The technique is illustrated by constructing the MOND density-potential pair for a triaxial galaxy model that, in the absence of deformation, reduces to the Hernquist sphere. Such analytical solutions are also relevant to test and validate numerical codes. Here we present a new numerical potential solver designed to solve the MOND field equation for arbitrary density distributions: the code is tested with excellent results against the analytic MOND triaxial Hernquist model and the MOND razor-thin Kuzmin disk, and a simple application is finally presented.
