Аннотация

The Chandler period of Mars is a new parameter determined from observational data that characterizes the properties of the planet’s interior. Numerical modeling of the period of the Chandler wobble of Mars was performed for a number of internal structure models that satisfy not only geodetic data (moment of inertia, tidal Love number k2), but also data obtained during a seismic experiment in 2019–2022. To reconcile the theoretical and observed values of the Chandler wobble, it is necessary to take into account the inelasticity of the mantle. To take into account the viscoelastic behavior of the interiors, the Andrade rheological model was used. It is demonstrated how the value of the Chandler period depends on the parameters of the rheological model.
