摘要

摘要-对巨行星与行星盘的相互作用进行了尼斯模型的数值建模，在该模型中，行星的初始轨道处于共振构型。除了标准的尼斯模型外，还考虑了行星区域内的小行星，并考虑了小行星盘的自重力。对行星系统的动态演化进行了研究，时间间隔与太阳系的寿命相当。已经找到了行星系保存数十亿年、行星的最终轨道接近现代轨道以及存在遥远的跨海王星天体的方案。

Study of Migration of Giant Planets and Formation of Populations of Distant Trans-Neptunian Objects in the Nice Model

Numerical modeling of the interaction of giant planets and the planetesimal disk was carried out for the Nice model, in which the initial orbits of the planets are in resonant configurations. In addition to the standard Nice model, planetesimals in the planetary region were considered and the self-gravity of the planetesimal disk was taken into account. The dynamic evolution of planetary systems has been studied over time intervals on the order of the lifetime of the Solar System. Options have been found in which planetary systems are preserved over billions of years, the final orbits of the planets are close to modern orbits and distant trans-Neptunian objects exist.

期刊介绍： Solar System Research publishes articles concerning the bodies of the Solar System, i.e., planets and their satellites, asteroids, comets, meteoric substances, and cosmic dust. The articles consider physics, dynamics and composition of these bodies, and techniques of their exploration. The journal addresses the problems of comparative planetology, physics of the planetary atmospheres and interiors, cosmochemistry, as well as planetary plasma environment and heliosphere, specifically those related to solar-planetary interactions. Attention is paid to studies of exoplanets and complex problems of the origin and evolution of planetary systems including the solar system, based on the results of astronomical observations, laboratory studies of meteorites, relevant theoretical approaches and mathematical modeling. Alongside with the original results of experimental and theoretical studies, the journal publishes scientific reviews in the field of planetary exploration, and notes on observational results.
