The Forces of Attraction Acting on the Body Inside the Disk (Силы притяжения, действующие на тело внутри диска)

Authors: Putenikhin P.V.

A hypothetical analogue of a disk galaxy is considered - a flat, extremely thin disk, inside which there is a some body, an analogue of a star. The density distribution function of the disk is given, according to which the forces acting on the body are calculated depending on its distance from the center of the disk. The calculated forces are used to construct the so-called rotation curve. By adjusting the disk density function, without involving external forces, it was possible to achieve that the disk rotation curve became close in shape to the rotation curve of the real Milky Way galaxy.
Рассмотрен гипотетический аналог дисковой галактики – плоский, предельно тонкий диск, внутри которого находится тело, аналог звезды. Задана функция распределения плотности диска, по которой вычислены силы, действующие на тело в зависимости от его удалённости от центра диска. По вычисленным силам построена так называемая кривая вращения. Корректировкой функции плотности диска, без привлечения внешних сил удалось добиться того, что кривая вращения диска стала по форме близка к кривой вращения реальной галактики Млечный Путь.
