Abstract

Some asteroids, comets, and planets (ACPs) are accelerated by giant planets and ejected from parent planetary systems with velocities of several kilometers per second. When leaving a disintegrating stellar cluster rather than only a parent star, ACPs form a spear-shaped cloud in space. Thereby, ACP spears are formed at the Sun, stars, and stellar clusters. Consequently, due to ACP spears, the boundaries of planetary systems are expanded to dozens of kiloparsecs in the course of time. This paper is focused on the numerical analysis of the orbital evolution of unbound ACPs in the Galaxy, which leads to their transformation to “cometary spears” near the Sun, stars, and stellar clusters. It has been shown that, over time, the ACP spears of stars are transformed to the rings around a center of the Galaxy.

太阳彗星长矛的时间演变

摘要

一些小行星，彗星和行星（ACP）被巨型行星加速，并以每秒几公里的速度从母行星系统中弹出。当离开可分解的恒星团而不是仅由母恒星组成时，ACP在太空中形成矛状的云。由此，在太阳，恒星和恒星群处形成了ACP矛。因此，由于使用了ACP矛，随着时间的流逝，行星系统的边界扩大到数十千帕秒。本文的重点是对银河系中非约束ACP轨道演变的数值分析，这将导致它们转变为太阳，恒星和恒星团附近的“彗星之矛”。研究表明，随着时间的流逝，ACP的长矛会转变为围绕银河系中心的环。
