| Title | Solar and Stellar dynamos: Concensus and divergences |
| Authors | Paul Charbonneau |
| Abstract | The past two decades have witnessed remarkable progress in the dynamo-based modelling and prediction of the solar magnetic activity cycle. However, and somewhat surprisingly, these advances have not yet led to a concensus view on the mode of operation of the solar dynamo, and even less so of stellar dynamos. In this talk I will briefly review some of these advances, including global magnetohydrodynamical numerical simulations as well as semi-empirical models based on reduced or mean-field magnetohydrodynamics. I will then survey the resulting diverging views on solar and stellar dynamos, and highlight potential paths to convergence for some of the more outstanding divergences. |
