Abstract

This paper presents a scenario of the evolution of OB associations and star clusters from formation to decay, in the process of which they turn into stellar streams moving in the disk and stellar “rings” around the galactic center. The scenario also includes the formation of stellar streams by galaxies absorbing their dwarf satellite galaxies. The simplest spatial kinematic models of evolution are constructed. It is shown that the stellar structures that appear in the models are similar to the observed stellar streams.

由于星团，天体协会和银河卫星的衰落而形成恒星流

摘要

本文介绍了OB关联和恒星团从形成到衰变的演变过程，在此过程中，它们变成了在盘中移动的恒星流和围绕银河系中心的恒星“环”。该场景还包括星系吸收其矮矮星系星系形成的恒星流。构建了最简单的进化空间运动学模型。结果表明，模型中出现的恒星结构与观测到的恒星流相似。
