We use a flux transport model to simulate the evolution of the Sun’s magnetic dipole moment, polar fields, and open flux under Maunder minimum conditions. Even when the rate of active region emergence is taken to be a factor of � 30 smaller than in recent solar cycles, regular polarity oscillations of the axial dipole and polar fields can be maintained if the speed of the poleward surface flow is reduced from � 20 to � 10 m s � 1 and the source flux emerges at very low latitudes (� 10 � ). The… Expand

The Global Solar Magnetic Field Through a Full Sunspot Cycle: Observations and Model Results
Based on 11 years of SOHO/MDI observations from the cycle minimum in 1997 to the next minimum around 2008, we compare observed and modeled axial dipole moments to better understand the large-scaleExpand
