Abstract The model of the galaxy is considered as a structure of the baryonic matter embedded into the hot dark matter. The dark matter is supposed to come into being from the decaying matter after the epoch of structure formation. The galaxy is divided into two regions. In the inner region, the baryonic matter predominates over the hot dark matter while in the outer region, the hot dark matter predominates over the baryonic matter. The motion of the test particle is bounded in the inner region (elliptic orbit) and unbounded in the outer region (parabolic orbit). Observational constraints on the proposed model are considered from the rotation curves of the galaxies: Milky Way, M33, NGC 2366 and IC 2574.

具有热暗物质的星系模型

摘要 星系模型被认为是一种嵌入热暗物质中的重子物质结构。暗物质应该是在结构形成时代之后的衰变物质中形成的。银河系分为两个区域。在内部区域，重子物质在热暗物质上占主导地位，而在外部区域，热暗物质在重子物质上占主导地位。测试粒子的运动在内部区域（椭圆轨道）有界，在外部区域（抛物线轨道）无界。从星系的旋转曲线考虑了对所提出模型的观测限制：银河系、M33、NGC 2366 和 IC 2574。
