Rotational Dependence of Large-scale Dynamo in Strongly-stratified Convection: What Causes It?

Youhei Masada, Takayoshi Sano

In a rigidly-rotating magnetohydrodynamic (MHD) system with convective turbulence, a large-scale dynamo, categorized as the ${\alpha }^2$-type, can be excited when the spin rate is large e…
