Iron snow dynamo models for Ganymede (vol 247, pg 248, 2015)

摘要

An error was detected in the numerical code that has been used for the simulations of dynamo models with a 'snow layer', in Ganymede's core which can explain the low observed quadrupole-to-dipole ratio in Ganymede's magnetic field. After correcting the error it is found that the stability of such strongly dipolar dynamos is even larger than found before. In contrast to a previous conclusion, they exist in a wide range of thicknesses for the snow layer. (C) 2015 Elsevier Inc. All rights reserved.
