Dynamo and the Adiabatic Invariant
Alexander M. Balk (University of Utah, Salt Lake City)
TL;DR
This paper investigates a dynamo mechanism in celestial bodies driven by magnetic Rossby waves, using an extra invariant in magnetohydrodynamics to explain how a strong background magnetic field is sustained.
Contribution
It introduces the concept of an extra invariant in MHD to explain the maintenance of magnetic fields in celestial dynamos, focusing on Rossby wave interactions.
Findings
The background magnetic field is maintained by the extra invariant.
Magnetohydrodynamics is linearized around a strong toroidal magnetic field.
The mechanism explains the sustenance of magnetic fields in planetary and stellar dynamos.
Abstract
The paper considers dynamo generated by a shallow fluid layer in a celestial body (planet or star). This dynamo is based on the extra invariant for interacting magnetic Rossby waves. The magnetohydrodynamics (MHD) is linearized on the background of strong toroidal magnetic field. The extra invariant is used to show that the background field is maintained.
