摘要
行星系日心经度和行星会合指数是行星系统运动的两大重要指标,在研究行星系统运动特征及演化规律方面具有特殊作用.行星会合指数可用于表征行星系统会合与分离的程度;行星系日心经度可用于表征行星系质心的准确方位,在研究行星系质心方位变化特征方面具有重要意义.本文对行星系日心经度的长期变化规律进行研究,利用索周法分析发现行星系日心经度具有准11.5年的主周期变化规律;利用功率谱分析表明近两千年的行星系日心经度数据中具有显著的11.893年的周期性变化规律;利用Morlet小波分析表明200年的数据中行星系日心经度周期规律分布在10~20年的时域内;三种分析方法均表明行星系日心经度具有准11.5年的变化规律.同时,借助索周法对行星系日心经度和行星系统对太阳引潮力进行周期对比分析,存在相似的周期性规律.因此,行星系日心经度和太阳引潮力指标均可用于分析太阳活动变化规律.为研究行星系统运动对太阳活动的影响方面具有一定意义.
The heliocentric longitude of planetary systems and the planet juncture index are two important indicators of the motion of planetary systems, which have a special role in the study of the motion characteristics and evolution of planetary systems. The planet juncture index can be used to characterize the degree of conjunction and separation of planetary systems;The heliocentric longitude of the planetary system can be used to characterize the exact orientation of the planetary system center of mass, which is important in the study of the variation of the planetary system center of mass orientation. This paper investigates the long-term variation of the heliocentric longitude of the planetary system, and finds that the heliocentric longitude of the planetary system have a quasi-11.5-year main period variation pattern by using the cycle exploring method;The power spectrum analysis shows that the heliocentric longitudes of the planetary system have a significant 11.893-year period variation pattern in the data of the last 2,000 years;Using Morlet wavelet analysis to show that the regular distribution of heliocentric longitude periods of planetary systems in the 200-year data is distributed in the time domain of 10~20 years. The three analysis methods all show that the heliocentric longitude of the planetary system has a quasi-11.5-year variation law. At the same time, the periodic comparison analysis of the heliocentric longitude of the planetary system and the solar tidal force of the planetary system with the help of the cycle exploring method shows the existence of similar periodic patterns. Therefore, the heliocentric longitude of the planetary system and the solar tidal force can be used to analyze the variation of solar activity. These have certain significance for studying the influence of planetary system motion on the solar activity.
