A possible explanation of the Maunder minimum from a flux transport dynamo model

Arnab Rai Choudhuri, Bidya Binay Karak

Abstract


We propose that the poloidal field at the end of the last sunspot cycle before the Maunder minimum fell to a very low value due to fluctuations in the Babcock--Leighton process. With this assumption, a flux transport dynamo model is able to explain various aspects of the historical records of the Maunder minimum remarkably well on choosing the parameters of the model suitably to give the correct growth time.
