Formula for the Chandler Period (Free Wobble of Planetary Bodies)
Geophysical Research LettersIf the rotational equilibrium of a planetary body is disturbed, the rotation pole responds with a cyclical motion. The duration of one cycle is referred to as the Chandler period, and, when viewed from space, the body wobbles.

Polar Motion Dynamics on Slow‐Rotating Venus: Signatures of Mantle Flow
AGU AdvancesWith its 1 day lasting 243 days on Earth, Venus is the slowest‐spinning planet in the Solar System and its rotational bulge is anomalously small. A rotational bulge stabilizes the orientation of planets. Having only a tiny stabilizer, the rotational pole

Cryospheric Excitation on the Earth's Chandler Wobble and Implications From a Warming World
Geophysical Research LettersLeveraging Gravity Recovery and Climate Experiment mascon products spanning from April 2002 to September 2023, we, for the first time, ascertain the substantial influence of cryospheric mass variations on Earth's Chandler wobble (CW).

Diminished Chandler Wobble After 2015: Link to Mass Anomalies in 2011
Geophysical Research LettersAbstract Observed polar motion after 2015 is dominated by the annual wobble, due to unprecedented amplitude reduction of the Chandler Wobble component. This change is likely due to suppression of the 433‐day‐period free wobble by geophysical excitation sources.

Measuring chandler wobble amplitude variations using IERS EOP C04 data [PDF]
Serbian Astronomical Journal, 2023 We analyzed the Earth's long-term polar motion using the time series IERS EOP C04 (International Earth Rotation and Reference Systems Service - IERS; Earth Orientation Parameters - EOP; Combination of four (04) techniques - C04), from 1984 to ...

Variations of seismic activity caused by the Chandler Wobble [PDF]
E3S Web of Conferences, 2019 The problem of the correlation of the global dynamic phenomenon “Chandler wobble” with the local dynamics in different parts of the Earth’s crust and lithosphere is wide of the solution.

Determining the moment of inertia of triaxial Mars with updated global gravity models
Earth and Planetary Physics, 2023 The principal moments of inertia (PMIs) with the principal axes are usually taken as the dynamic figure parameters of Mars; they can be deduced from satellite-observed degree-two gravitational potentials in recent global gravity models and from the ...

Geodesy and Geodynamics, 2020 Until now, the calculation of the principal inertia moment of the triaxial three-layered Earth mainly adopts the scaling method. This method assumes that the corresponding principal inertia axes of the layers coincide each other, but this is not the case.
