Solar differential rotation reproduced with high-resolution simulation

The Sun rotates differentially with a fast equator and slow pole. Convection in the solar interior is thought to maintain differential rotation. However, although many numerical simulations have been conducted reproduce rotation, previous high-resolution calculations parameters fall into anti-solar (fast pole) rotation regime. Consequently, we still do not know true reason why has fast-rotating equator. While construction of requires strong rotational influence on convection, able achieve situation without any manipulations. problem called convective conundrum. convection were different from observations. Here, show that calculation succeeds reproducing solar-like Our indicate magnetic field generated by small-scale dynamo significant impact thermal convection. successful reproduction achieved our an essential step understanding cause most basic nature activity, specifically, 11-year cycle sunspot activity.
