Extended Data Figure 7: Planetary magnetic parameters calculated from the dynamo generation model.
From: Long-lived magnetism from solidification-driven convection on the pallasite parent body
a, Local Rossby number, Rol, showing the combination of parameters resulting in predominantly dipolar (red region) to multipolar (blue region) fields. b, Magnetic Reynolds number, Rem, showing the combination of parameters that do (blue region) and do not (red region) result in dynamo activity. c, Dipolar Lorentz number, Lodip, showing the combination of parameters that do (blue region) and do not (red region) produce Lodip > 10−5. A four-hour rotation period is highlighted in each figure.
