On a possible connection between Chandler wobble and dark matter

TL;DR

This paper explores a novel hypothesis linking the Earth's Chandler wobble to interactions with a hypothetical dark matter ellipsoid, proposing a potential connection that could explain geophysical phenomena.

Contribution

It introduces a new model suggesting dark matter interactions influence Earth's polar motion and examines implications for Earth's magnetic field and heat generation.

Findings

Reproduces Chandler wobble epochs using dark matter parameters

Suggests dark matter may impact Earth's geomagnetic dynamo

Implications for Earth's heat production and geophysical processes

Abstract

Chandler wobble excitation and damping, one of the open problems in geophysics, is treated as a consequence in part of the interaction between Earth and a hypothetical oblate ellipsoid made of dark matter. The physical and geometrical parameters of such an ellipsoid and the interacting torque strength is calculated in such a way to reproduce the Chandler wobble component of the polar motion in several epochs, available in the literature. It is also examined the consequences upon the geomagnetic field dynamo and generation of heat in the Earth outer core.
