Abstract

On the basis of gravitational data, seismic data and geochemical models of the mineralogical composition of the mantle of Mars, the internal structure models were constructed. The effect of the mantle mineralogical composition on the model value of the Chandler Wobble period was investigated. Andrade rheology was used to account for the inelasticity of the interiors when calculating the tidal Love number k2 and the period of Chandler Wobble. Variations in the composition of the planet's mantle lead to a change in the value of the period of the Chandler Wobble by 1–1.5 days.
