This paper presents a new method of calculating dark matter density profiles for superthin axial symmetric galaxies without a bulge. This method is based on a simple physical model, which includes an infinitely thin galactic disc immersed in a spherically symmetric halo of dark matter. To obtain the desired distribution density, it suffices to know a distribution of visible matter surface density in a galaxy and a dependence of angular velocity on the radius. As a byproduct, the well-known expression, which reproduces surface density of a superthin galaxy expressed through a rotation law, was obtained.

超薄星系中的暗物质分布

本文提出了一种新的计算超薄轴向对称星系而没有凸起的暗物质密度分布的方法。该方法基于简单的物理模型，该模型包括浸没在暗物质的球形对称光晕中的无限薄的银河盘。为了获得期望的分布密度，只要知道星系中可见物质表面密度的分布以及角速度对半径的依赖性即可。作为副产物，获得了公知的表达式，该表达式再现了通过旋转定律表达的超薄星系的表面密度。
