摘要

金星是地球最近的邻居,大小与地球相近,是执行某些类型任务的理想场所。这些任务既包括科学任务,如太阳物理和空间天气监测,也包括以防御为重点的任务,如监测地球的轨道路径以防流星体威胁。对太阳-金星系统中的周期轨道所做的研究十分有限。要了解哪些轨道可用于此类任务,第一步是确定太阳-金星系统中的共振周期轨道族,并对这些轨道进行稳定性分析。这项研究工作确定了太阳-金星系统中的 90 个周期性共振轨道及其相关轨道族。这些轨道是在圆形受限三体问题(CR3BP)动力学模型中发现的,并将太阳辐射压力作为一种扰动。周期性轨道是利用波恩卡雷映射找到的,而族则是利用通过不同雅可比常数的延续方法生成的。计算族中每个轨道的稳定性,评估每个轨道的特征值结构,以确定族何时越过分岔点。这项研究工作旨在生成太阳-金星系统内共振轨道的目录,同时为每个共振轨道族提供稳定性和分岔信息。

Identification and analysis of interior and exterior resonant orbits in the Sun–Venus system
With Venus being Earth’s nearest neighbor and it being similar in size to Earth, it is the ideal candidate for certain mission types. These missions range from scientific, such as helio-physics and space weather monitoring, to defense focused, such as monitoring Earth’s orbital path for meteoroid threats. Limited research has been done on the periodic orbits in the Sun–Venus system. The first step to understanding which orbits could be useful for such a mission is to identify families of resonant periodic orbits in the Sun–Venus system and conduct a stability analysis on these orbits. This research work identifies 90 periodic, resonant orbits in the Sun–Venus system and their associated families of orbits. The orbits are found within the Circular Restricted 3 Body Problem (CR3BP) dynamical model with solar radiation pressure included as a perturbation. The periodic orbits are found using Poincaré maps, and the families are generated using a continuation method that steps through different Jacobi constants. The stability for each orbit in the family is calculated and the structure of the eigenvalues for each is assessed to determine when the family has crossed a bifurcation point. This research work seeks to generate a catalog of resonant orbits within the Sun–Venus system while providing stability and bifurcation information for each resonant orbit family.

期刊介绍: Icarus is devoted to the publication of original contributions in the field of Solar System studies. Manuscripts reporting the results of new research - observational, experimental, or theoretical - concerning the astronomy, geology, meteorology, physics, chemistry, biology, and other scientific aspects of our Solar System or extrasolar systems are welcome. The journal generally does not publish papers devoted exclusively to the Sun, the Earth, celestial mechanics, meteoritics, or astrophysics. Icarus does not publish papers that provide "improved" versions of Bode''s law, or other numerical relations, without a sound physical basis. Icarus does not publish meeting announcements or general notices. Reviews, historical papers, and manuscripts describing spacecraft instrumentation may be considered, but only with prior approval of the editor. An entire issue of the journal is occasionally devoted to a single subject, usually arising from a conference on the same topic. The language of publication is English. American or British usage is accepted, but not a mixture of these.
