地球空间环境中的共振

Resonances in the Earth's Space Environment

Alessandra Celletti, Catalin Gales, Christoph Lhotka

摘要:

我们研究地球周围空间区域中共振的存在。我们考虑一个无质量的物体(例如,一个尘埃粒子或一个小的空间碎片)受到不同的力:地球势的引力,太阳和月亮的影响。我们区分了不同类型的共振:田面共振是由于涉及粒子的公转和地球自转的可调和性,半长期共振包括月球和太阳的平均异常的变化率,而长期共振仅取决于近地点和扰动天体升交点的辐角的变化率。我们这样的共振的特点,给出精确的陈述的区域中可以找到的共振,并提供一些具体的可解释性关系的例子。

英文摘要:

We study the presence of resonances in the region of space around the Earth. We consider a massless body (e.g, a dust particle or a small space debris) subject to different forces: the gravitational attraction of the geopotential, the effects of Sun and Moon. We distinguish different types of resonances: tesseral resonances are due to a commensurability involving the revolution of the particle and the rotation of the Earth, semi-secular resonances include the rates of variation of the mean anomalies of Moon and Sun, while secular resonances just depend on the rates of variation of the arguments of perigee and the longitudes of the ascending nodes of the perturbing bodies. We characterize such resonances, giving precise statements on the regions where the resonances can be found and provide examples of some specific commensurability relations.
