Abstract

We present a three-dimensional model of the evolution of the asteroid–cometary–planetary (ACP) component of the Solar System under the gravitational influence of Jupiter. We demonstrate the origin of the Kuiper belt of the Sun, the Oort cloud of the Sun and Jupiter, as well as the ACP “spear,” which becomes elongated with time and transforms into a “ring” of ACP objects along the trajectory of the Sun orbiting the Galaxy center. When generalizing to the case of the Galaxy, we conclude that a noticeable portion of ACP objects turn out to be unbound with the host stars and form a field of free asteroids, comets, and planets of the Galaxy. Galaxies with small masses (M < 108 M) lose a part of their unbound ACP material to the intergalactic space of their clusters and possess galactic ACP spears.

行星系统产生未结合的彗星和行星

摘要

我们提出了在木星引力作用下太阳系小行星-彗星-行星(ACP)分量演化的三维模型。我们展示了太阳柯伊伯带的起源,太阳和木星的奥尔特云以及ACP“矛”的起源,该矛随着时间的流逝而变长,并沿ACP物体的轨迹转变为ACP对象的“环”。太阳围绕银河系中心运行。当归纳为银河系的情况时,我们得出结论,ACP物体的显着部分原来与宿主恒星解除了结合,形成了一个自由的小行星,彗星和银河系行星的区域。用小的质量(星系中号<10 8 中号)将部分未结合的ACP物质损失到星团的星际空间中,并拥有银河ACP长矛。
