摘要

摘要介绍了火星钱德勒摆动周期数值建模的结果，这些结果是针对一组内部结构模型得出的，这些模型满足目前所有可用的可观测数据：大地测量（平均半径、质量、惯性矩、潮汐爱数 k2）以及地震数据处理获得的地壳厚度和地核半径值。在计算潮汐爱数 k2 和钱德勒摆动周期的模型值时，使用了安德拉德流变学来考虑非弹性因素。结果表明，爱数 k2 和钱德勒周期的模型值如何取决于安德拉德流变参数和所采用的粘度分布。

Influence of Mantle Inelasticity on the Model Value of the Chandler Wobble Period of Mars

Abstract—

The results of numerical modeling of the values of the Chandler wobble period of Mars have been presented for a set of internal structure models that satisfy all currently available observable data: geodetic (average radius, mass, moment of inertia, tidal Love number k₂) and crustal thickness and core radius values obtained from seismic data processing. Andrade rheology was used to take into account inelasticity when calculating model values of the tidal Love number k₂ and the Chandler wobble period. It has been shown how the model values of the Love number k₂ and the Chandler period depend on the Andrade rheological parameter and the adopted viscosity distribution.

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.
