Local Flow Estimation at the top of the Earth's Core using Physics Informed Neural Networks

Naomi Shakespeare-Rees, Philip W. Livermore, Christopher J. Davies +4

The Earth's main geomagnetic field arises from the constant motion of the fluid outer core. By assuming that the field changes are advection-dominated, the fluid motion at the core…

Reconstructions of Jupiter's magnetic field using physics informed neural networks

Philip W. Livermore, Leyuan Wu, Longwei Chen +1

Magnetic sounding using data collected from the Juno mission can be used to provide constraints on Jupiter's interior. However, inwards continuation of reconstructions assuming zer…

Interannual Magneto-Coriolis modes and their sensitivity on the magnetic field within the Earth's core

Felix Gerick, Philip Livermore

Linear modes for which the Coriolis acceleration is almost entirely in balance with the Lorentz force are called Magneto-Coriolis (MC) modes. These MC modes are thought to exist in…

Wavefield reconstruction inversion modelling of Marchenko focusing functions

Ruhul F. Hajjaj, Sjoerd A. L. de Ridder, Philip W. Livermore +1

Marchenko focusing functions are in their essence wavefields that satisfy the wave equation subject to a set of boundary, initial, and focusing conditions. Here, we show how Marche…

Recent north magnetic pole acceleration towards Siberia caused by flux lobe elongation

Philip W. Livermore, Christopher C. Finlay, Matthew Bayliff

The wandering of Earth's north magnetic pole, the location where the magnetic field points vertically downwards, has long been a topic of scientific fascination. Since the first in…

Constraints on the magnetic field within a stratified outer core

Colin M Hardy, Philip W Livermore, Jitse Niesen

Mounting evidence from both seismology and experiments on core composition suggests the existence of a layer of stably stratified fluid at the top of Earth's outer core. In this wo…

Penetration of boundary-driven flows into a rotating spherical thermally-stratified fluid

Grace A. Cox, Christopher J. Davies, Philip W. Livermore +1

Motivated by the dynamics within terrestrial bodies, we consider a rotating, strongly thermally stratified fluid within a spherical shell subject to a prescribed laterally inhomoge…

Three-dimensional solutions for the geostrophic flow in the Earth's core

Colin M. Hardy, Philip W. Livermore, Jitse Niesen +2

In his seminal work, Taylor (1963) argued that the geophysically relevant limit for dynamo action within the outer core is one of negligibly small inertia and viscosity in the magn…

A new identity linking coefficients of a certain class of homogeneous polynomials and Gauss hypergeometric functions

Philip W. Livermore, Glenn R. Ierley

In investigating the properties of a certain class of homogeneous polynomials, we discovered an identity satisfied by their coefficients which involves simple 2F1 Gauss hypergeomet…
