On the Chandler wobble of Mars

The possibility of determination of the aggregative state and the radius of the Martian core by Chandler wobble data is discussed. The polar motion under consideration is excited by the Martian atmosphere and convective flow in the liquid core. The effects of the liquid core and anelasticity of the mantle on the period and quality factor of Chandler wobble are calculated. For the set of trial Martian models the corrections for the effects of the liquid core and anelasticity of the mantle to the period of Chandler wobble are of the order of 8 days, and the values of the quality factor are of the order of 100–200. The lengthening of the Chandler period due to the anelasticity of the interiors of Mars can reach: ≈2–5 days.
