Intermittency as a possible underlying mechanism for solar and stellar variability
Abstract
Description
We briefly discuss the status of the intermittency hypothesis, according to which the grand minima type variability in solar-type stars may be understood in terms of dynamical intermittency. We review concrete examples which establish this hypothesis in the mean-field setting. We discuss some difficulties and open problems regarding the establishment of this hypothesis in more realistic settings as well as its operationally decidability.
