摘要：
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 k(2)) 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 k(2) and the Chandler wobble period. It has been shown how the model values of the Love number k(2) and the Chandler period depend on the Andrade rheological parameter and the adopted viscosity distribution.
